You could do the following
<Button Command={Binding MyCommendInTheController, Source={StaticResource
controller}/>
Also, you could use the CallMethodAction and completely forget about the use
of Commands. I think Actions are way more flexible than commands. If you
have to use Commands, you could use the InvokeCommandAction if you need to
use a different trigger.
As a side note, I would avoid communication between the view and the
controller. All my view has to know about is the ViewModel.
