title: Kendo MultiSelect update of ngmodel
body: <p>I'm trying to add one button for adding values to ngmodel of kendo's multi select:</p>
  
  <pre><code>&lt;div ng-controller="MyCtrl"&gt;
    &lt;select id='my' kendo-multi-select k-options="selectOptions" k-ng-model="selectedIds"&gt;&lt;/select&gt;
    &lt;p ng-show="selectedIds.length"&gt;Selected: {{ selectedIds }}&lt;/p&gt;
    &lt;button ng-click="addSelectedId()"&gt;Add selected id&lt;/button&gt;
    &lt;input ng-model="enteredId" /&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Here is controller</p>
  
  <pre><code>  function MyCtrl($scope) {
        $scope.selectOptions = {
            placeholder: "Select products...",
            dataTextField: "ProductName",
            dataValueField: "ProductID",
            autoBind: false,
            dataSource: {
                type: "odata",
                serverFiltering: true,
                transport: {
                    read: {
                        url: "http://demos.telerik.com/kendo-ui/service/Northwind.svc/Products",
                    }
                }
            }
        };
        $scope.selectedIds = [ 4, 7];
         $scope.addSelectedId = function() {
            $scope.selectedIds.push(parseInt($scope.enteredId));
            console.log($scope.selectedIds);
         };
    }
  </code></pre>

  <p>When added to selectedIds, nothing gets added to dropdown select placeholder. Any ideas?</p>
