This is exactly the problem I am trying to solve. Would you please be so
kind to elaborate?

Are you telling us we should:

1. create a callback function.
2. create a vtkCallbackCommand object
3. assign the callback function to vtkCallbackCommand (ie
vtkCallbackCommand->SetCallback( callback ))

4. what next? where do we use AddObserver?

Thank you in advance!
