Hi, thanks Rostislav for the reference. The cited message also applies in this case.
If I understood the set-up right, implementing your own selection provider for your renderer is the way to go. I assume the selection in your current code is not fired because the data manager is not focused and hence its selection provider is not "active". Setting the selection on the data manager will hence not trigger selection changed events.
