Rename new node and post it to server

[Jan]

Hi all, I have following scenario:

I creted new node in radTreeView (by javasrcipt), then i allow user to rename it by startEdit method and after that i have set OnNodeEdit server event. 

But it not fired. Postback is posted, by not fired OnNodeEdit.

This is my client-side snippet:

                    tree.trackChanges();

                    var node = new Telerik.Web.UI.RadTreeNode();

                    if (args.get_dropPosition() == "over") destNode.get_nodes().add(node);
                    if (args.get_dropPosition() == "above") insertBefore(destNode, node);
                    if (args.get_dropPosition() == "below") insertAfter(destNode, node);
                    node.set_text("New category");
                    var attributes = node.get_attributes();
                    attributes.setAttribute('CreateNewNode', true);

                    args.set_cancel(true);
                    tree.commitChanges();
                    node.startEdit();

I'm doing that onDroping. 

Any ideas? Many Thanks!!!
