Philosophically speaking buttons don't latch. You push the button, an 
event is generated, and the call-back handles the event to do something 
in your project.

You might try setting a global variable on the button-push event.

Or, if I understand you, you might want to use a configurable, like a 
radio button or a check box, either of which are designed to be "latched".
