Client Side Event After Node Dropped

GoDiagram (6 and previous)
1

This event fires fine after a new node is dragged and dropped onto a GoView:

BackgroundSelectionDropped
What can I do to cause a client-side function to fire immediately after this event finishes on the server? I need to prompt the user for information after they create a new node but I can't find anything that fires on the client side.
Thanks-
Dave

Look at what NodeLinkDemo does with function goOnLoad. It prompts for a label on a drop from the palette.
