building a telerik treeview clientside works but doesnt expand showing children
===

I have a Treeview.  This treeview gets populated client side with children in javascript using something along the lines of:

    treeView.trackChanges();
    var newNode = new Telerik.Web.UI.RadTreeNode();
    newNode.set_text(node);
    hasParent.get_nodes().add(newNode);
    treeView.commitChanges();

The downside is that when looking at the client, the tree doesnt expand, to show these children.  Am i missing a step?
