I guess the reason this is missing, is that nobody ever needed it. In
my opinion, the need of a cancel-callback is a sign of a code-smell

However you can add a method like the following one, to get the
desired behavior:

WASubmitButtonTag>>cancelCallback: aBlock
	self attributes at: 'name' put: (canvas callbacks
registerCancelActionCallback: aBlock)
