I'm not sure that what you're trying to do will work. I suspect it won't with one big reason being Columns don't implemenet the same onBrowserEvent that Widgets do.
What you probably need to do is redesign your widget as a Cell. Then when you need to use it as a widget, push that cell into CellWidget. I'm fully aware of how complicated this could become, but I think this will be your best option.
