Refresh a particular div without reloading the page?

how to refresh the just the ember-selectize div without reloading the whole page.

If you update the author model ember-selectize will update without reloading the page. This seems to be the same bug as the ember-cli-pagination one. I think you somewhere have a Ember.computed filter or something that is not listening for change on the correct values. Try skipping this Ember.computed for the test.

how should i update the author in the model.

my code—>

 {{ember-selectize
      multiple="true"
      filter="true" 
      remove-item="itemRemoved"
      content=roles
      name="roleIds"
      optionValuePath="content.id"
      optionLabelPath="content.name"      
      update-filter="roleFilterUpdate"
      add-item="selectedRole"
      selection=content.roleIds
      placeholder="--Select--"
      }}

export default Ember.Controller.extend({

 removedValue:[],
itemRemoved:function(removedItem){
        this.get('removedValue').push(removedItem.id);
    },
    Close: function() {  
       // console.log(">>"+this.get('content.roleIds'));
       let self = this;
       var array = [];
        var roleLength = self.get('content.roleIds');
        roleLength.forEach(function(roleeach) {
            array.push(roleeach.get('id'));
         });
        var finalValue = array.concat(this.get('removedValue'));
        self.set("roleLength",finalValue);
        self.get('model').rollbackAttributes();      
    }
  }

});

i dont want to update the value without saving . so, while saving i m retrieving all deleted values… how to get bck all the values???

You can see this in action by going to in one browser to https://bloggr.exmer.com/ login and select edit on some post. Go in an other browser to https://bloggr.exmer.com/ login and add an Author. Go back to the first browser and see you Author there without reloading the page. I recommend not to use Safari for this test because it keeps asking for more storage memory. Edge, Chrome, Firefox, IE etc. are all fine.

My example is with saving. Have not used the roleback options but values are updated without saving out of the box. Not sure I can help with this.
