TreeList expander control disappears or does not work if control is reloaded with new TreeListDataSource

[George]

Hi,

I have attempted to reload a Kendo TreeView control with a new TreeViewDataSource...

function reloadLists() {

    console.log("In reloadLists():");

    var ds2 = new kendo.data.TreeListDataSource({ data: actionsV2, schema: 
                                                  { model: Models.TREELISTMODELTWO } });
    ds2.read();
    var vw2 = ds2.view();
    _view.set("actionsObserv", vw2);
    $("#actionsTreelist").data("kendoTreeList").setDataSource(_view.get("actionsObserv"));
}
 

...but when the new dataSource is loaded I noticed the expander arrows do not work. The top one disappears when clicking on it:

The other ones do not function, there is no change when I click on them. I cannot contract an expanded branch, nor can I expand a contracted branch. What am I missing? Is this a bug? Here is a link to the Kendo Dojo  with an example:

Kendo TreeList Reload List Example | Kendo UI Dojo (telerik.com)

Thanks again for your help and patience ^__^

I don't need:

ds2.read();
var vw2 = ds2.view(); 

function reloadLists() {

    console.log("In reloadLists():");

    var ds2 = new kendo.data.TreeListDataSource({ data: actionsV2, schema: 
                                                  { model: Models.TREELISTMODELTWO } });
    ds2.read();//***DON'T NEED THIS ***
    var vw2 = ds2.view();//***DON'T NEED THIS ***
    _view.set("actionsObserv", vw2);
    $("#actionsTreelist").data("kendoTreeList").setDataSource(_view.get("actionsObserv"));

}

Force of habit. Now it works as expected.
