Looking at the source for the PmwCounter it doesn't look like it exposes 
the buttons callbacks.

I think the best way to do this would be to provide a validator method 
to the Counter's entryfield.  The validator gets called whenever the 
entryfields value changes.

Example validator methods are included in the Pmw documentation.
