Add a node to ClientChanges/ClientOperation

[laplace82]

I have a RadTreeview and i change some of its nodes attributes in client-mode: how can i add the node modified to the collection clientChanges so i  can retrieve this modifications on server side?

Thanks.

P.S.: ClientChanges works well (add the node to its collection) if i drag&drog a node by client-side, if i rename a node always client-side but not if i only change a node attribute in client-side.
