Angular-Kendo UI treeview, issue on node expansion

I'm facing this alleged Kendo UI treeview bug in the Angular version. It's specific to the k-template option.

The bug shows up on their online demo - http://demos.telerik.com/kendo-ui/treeview/angular

Just expand Item 2, and suddenly the text becomes {{dataItem.text}}.

Here's the html I'm using on my page:

 <div id="treeview" kendo-tree-view="nav.treeview"             
                k-options="nav.treeOptions"
                k-data-source="nav.reportsTreeDataSource"
                k-on-change="nav.onTreeSelect(dataItem)">         
    <span k-template>
        <span data-toggle-tree-icons></span>
    </span>       
 </div>

kendo treeview

Has anyone comes across this, or found an updated Kendo lib ?

thanks, Bob

Solution

The k-template issue has been rectified in the last Kendo UI release, .1328. This demo here a still a version behind however - http://demos.telerik.com/kendo-ui/treeview/angular .
