Kendo MultiSelect update of ngmodel - angularjs

Question

I'm trying to add one button for adding values to ngmodel of kendo's multi select:
<div ng-controller="MyCtrl">
<select id='my' kendo-multi-select k-options="selectOptions" k-ng-model="selectedIds"></select>
<p ng-show="selectedIds.length">Selected: {{ selectedIds }}</p>
<button ng-click="addSelectedId()">Add selected id</button>
<input ng-model="enteredId" />
</div>
Here is controller
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);
};
}
Plunker is here:

When added to selectedIds, nothing gets added to dropdown select placeholder. Any ideas?

You need to add k-rebind="selectedIds" in your html code
HTML:
<div ng-controller="MyCtrl">
<select id='my' kendo-multi-select k-options="selectOptions" k-ng-model="selectedIds" k-rebind="selectedIds"></select>
<p ng-show="selectedIds.length">Selected: {{ selectedIds }}</p>
<button ng-click="addSelectedId()">Add selected id</button>
<input ng-model="enteredId" />
</div>
