[BUG] Custom DomComponent & Block let all elements duplicated

I created a Custom Block:

bm.add('imagemLink', {
    label: 'Imagem Link',
    content: {
        activeOnRender: 1,
        droppable: false,
        type: 'imagemLink',
        content: '<a title="" link=""><img src="img/model.png"></img></a>'
    }
});

and a Custom DomComponent:

domComps.addType('imagemLink', {
  // Define the Model
  model: defaultType.model.extend({
        defaults: {
            tagName: "div",
            type: "",
            name: "",
            removable: !0,
            draggable: !0,
            droppable: !0,
            badgable: !0,
            stylable: !0,
            "stylable-require": "",
            unstylable: "",
            highlightable: !0,
            copyable: 0,
            resizable: !1,
            editable: !0,
            layerable: !0,
            selectable: !0,
            hoverable: !0,
            void: !1,
            state: "",
            status: "",
            content: "",
            icon: "",
            style: "",
            attributes: "",
            classes: "",
            script: "",
            traits: ["id", "title"],
            propagate: "",
            toolbar: null
        },
  }),
  view: defaultType.view.extend({
            events: {
            'click': function(){
                var openSmBtn = editor.Panels.getButton('views', 'optionsBlock');
                openSmBtn.set('active', 1);
            },
            'dblclick': function(){
                editor.select(this.model);
                selecionado = this.model;
                editor.runCommand("open-assets", {
                    onSelect: function (t) {
                        var newSrc = t.attributes.src;
                        conteudoImagemLink = $(editor.getSelected().toHTML());
                        var elConteudoImagem = $($(conteudoImagemLink[0]).children('a')).children('img');
                        $(elConteudoImagem)[0].src = newSrc;
                        editor.getSelected().set('content', conteudoImagemLink[0].innerHTML);
                        editor.DomComponents.render();
                        editor.select(null);
                        selecionado = null;
                        editor.Modal.close(), editor.AssetManager.setTarget(null);
                    }
                });
            },
            'mouseenter': function(){
                if(!selecionado){
                    editor.select(this.model);
                    var openSmBtn = editor.Panels.getButton('views', 'open-blocks');
                    openSmBtn.set('active', 1);
                }
            },
            'mouseleave': function(){
                if(!selecionado){
                    editor.select(null);
                    var openSmBtn = editor.Panels.getButton('views', 'open-blocks');
                    openSmBtn.set('active', 1);
                }else{
                    editor.select(selecionado)
                }
            }
        },
    })
});

And a Custom Command (I found where error is happening):

editor.Commands.add('opcoesBloco', {
    run: function(editor, sender){
        const bm = editor.BlockManager;
        const pn = editor.Panels;
        var selectedBlock = editor.getSelected();
        const id = 'views-container';
        const mkeditorCustom = document.createElement('div');
        const panels = pn.getPanel(id) || pn.addPanel({ id });
        if(selectedBlock){
            if(blocoSelecionado.attributes.type == "imagemLink"){
                const divTotal = document.createElement('div');
                divTotal.className = 'col-md-12';
                const divUm = document.createElement('div');
                divUm.className = 'col-md-4';
                const divDois = document.createElement('div');
                divDois.className = 'col-md-8';
                var elLink = $(blocoSelecionado.attributes.content);
                var elImagem = $(elLink).children('img');
                var nomeArquivo = elImagem[0].src.split('/').slice(-1)[0];

                arquivo.style = 'display: block; color:#000000';

                const imagem = document.createElement('img');
                imagem.src = elImagem[0].src;
                imagem.style = 'max-width: 100%';
                tamanho.innerHTML = imagem.naturalWidth + ' x ' + imagem.naturalHeight;
                const botao = document.createElement('a');
                botao.style = "margin-top:10px; color: #848080; cursor: pointer;text-decoration: underline; font-size: 15px;";
                botao.innerHTML = "Change Image";
                conteudoImagemLink = $(blocoSelecionado.toHTML());
                botao.onclick = function(){
                    editor.runCommand("open-assets", {
                        onSelect: function (t) {
                            var newSrc = t.attributes.src;
                            $($(divUm).children('img')[0])[0].src = newSrc;
                            var nomeNovaImagem = newSrc.split('/').slice(-1)[0];
                            $(divDois).children('span')[0].innerHTML = nomeNovaImagem;

When I set the new link for child img, any block I add to editor, is adding twice, and when I select this duplicated block, both are selected and changed:
