can't able to remove the added traits properties[QUESTION]

Hi, I can able to add the traits properties dynamically by using the following code.

 this.get('traits').add({
             type: 'text',
             label: 'entity',
             name: 'type',
             changeProp: 1
           }, { at: 2 });

but the following code to remove the type name is not working

this.get('traits').remove('type');

my complete traits are

comps.addType('link', {
      model: defaultModel.extend({
        defaults: Object.assign({}, defaultModel.prototype.defaults, {
          draggable: '*',
          droppable: false,
          traits: [{
            label: 'Name',
            name: 'name',
            type: 'text',
            changeProp: 1
          }, {
            type: 'checkbox',
            label: 'isDynamic',
            name: 'linkCheckboxModal',
            changeProp: 1
          }, {
            type: 'linkButton',
            label: 'Link',
            name: 'linkButton'
          }],

        }),
        init() {
          this.listenTo(this, 'change:linkCheckboxModal', this.dynamicModal);
        },
        dynamicModal() {
         this.changed['linkCheckboxModal']);
          if (this.changed['linkCheckboxModal']) {
            const component = screenGlobalVariable.editor.getSelected();
            this.get('traits').add({
              type: 'text',
              label: 'entity',
              name: 'type',
              changeProp: 1
            }, { at: 2 });
            screenGlobalVariable.editor.TraitManager.getTraitsViewer().render();
          } else {
            this.get('traits').remove('type');
            screenGlobalVariable.editor.TraitManager.getTraitsViewer().render();
          }
        }
        },
        {
          isComponent: function (el) {
            if (el.tagName === 'A') {
              return { type: 'link' };
            }
          },
        }),

      // Define the View
      view: defaultType.view,
    });

can anyone please help me
