The message watcher only shows the following events being triggered:

mouseDown
textUpdate
mouseUp
mouseMove

so you could use:

     def on_Spinner_textUpdate(self, event):
	print "Spinning..."

but unless you are keeping track of the spinner's value before and after 
the textUpdate it does not look like you can tell whether you 
are...er...spinning up or down.
