Why does the context menu not appear when right-clicking a node in a checked box tree?

I have a checked box tree with a context menu that allows the user to delete the selected node. The context menu only appears when I right-click in open space away from the node. I am unable to right-click the node itself to open the context menu.

I have attached a simple example tree to illustrate.

uitreenodes each can have their own uicontextmenus, so you need to associate the context menu with the nodes rather than with the uitree itself. See the attached modified app.
