如何更新k-ng-model（也称为与ng-model相似的双向绑定）

Question

Does Kendo k-ng-model support two-way binding, and if not, what is the best approach to simulate it?

---

A bit of context:

In angular, when an update to ng-model is done, all interested parties are updated (eg view is refreshed). In kendo, when using k-ng-model, I cannot find a way of doing the same, where I would want to set the value from the controller / directive directly.

Here is an example: Coding Dojo

And, just in case, the code as well:

 <input kendo-auto-complete 
        k-ng-model="vm.kendoSelection" 
        ng-model="vm.angularSelection"                     
        k-data-source="vm.countryNames" 
        k-data-value-field="'name'"
        k-data-text-field="'name'" />

sample controller:

  angular.module("MyApp", [ "kendo.directives" ])
         .controller("Controller", function(){                  
             // just some data source
             this.countryNames = [
                { name: "Albania" },
                { name: "Andorra" }
              ];

             // how to set the k-ng-model here, so that it is also propagated properly (like on 
             // the view, and that other events like k-on-change work)?
             this.kendoSelection = { name: "Albania" };                  
          });

EDIT:

Even after the answer from Dion Dirza, the k-on-change is not firing (altough it is a solution in good direction)

Answer 1

As documentation said, that k-ng-model should store or return actual type of widget value. Therefore to make your variable kendoSelection work, you should define it as actual type of widget value , which in this case is array type for auto-complete widget.

Change your code

vm.kendoSelection = [{ name: "Albania" }];

Because you are storing object array here so your variable should be array of object. Put a caution here that your object should contains a property that defined as widget data-value-field which it will be used for comparison with current data source.
