            model: dModel.extend(
                {
                    init() {
                        this.listenTo(this, 'change:type', this.doStuff);
                    },
                    doStuff() {       
                    },
                    defaults: Object.assign({}, dModel.prototype.defaults, {
                        traits: [
                            {
                                name: 'button',
                                label: 'Add',
                                type: 'buttonModal',
                                changeProp: 1

                            },
                            {
                                type: 'select',
                                label: 'Page',
                                name: 'type',
                                options: this.pagesList,
                                changeProp: 1,
                            },
                        ],
                    }),
                },

                {
                    isComponent: function (el) {
                        if (el.tagName == 'div') {
                            return { type: 'asset' };
                        }
                    },
                },
            ),

            view: dView,
        });
