Custom traits value is not set in Code

@HarshOB show how you create the custom trait

Here is the code:

editor.TraitManager.addType('customConent1', {
  getInputEl: function () {
    if (!this.inputEl) {
      var input = document.createElement('select');
      input.setAttribute("id", "Div1");
      input.setAttribute("name", "Div1");
      input.setAttribute("style", "background:#363636");
      $.each(partialOptions, function (key, value) { //partialOptions is an array
        var group = $('<optgroup label="' + key + '" />');
        $.each(value, function () {
            $('<option />').html(this.name).appendTo(group);
        });
        group.appendTo(input);
      });
      input.value = this.target.get('customConent1');
      this.inputEl = input;
    }
    return this.inputEl;
  },
});

@HarshOB try to see if the change actually triggers

editor.TraitManager.addType('customConent1', {
  	events:{
    	'change': 'onChange'
 	},

	onChange() {
		console.log('changed');
    	this.model.set('value', this.getInputEl().value);
 	},

  getInputEl: function () {
	...
