[Seaside] checkbox callbacks

[Alexander Lazarević]

#serializeThisWithHidden works nicly to update the internal state, but
I can't wrap my mind around on how to update the checkboxes.
Now the following obviously won't work but hopefully reveals my intentions:

renderContentOn: html
	html form: [
		html checkbox
			onChange: (html jQuery ajax serializeThisWithHidden);
			value: self isChecked;	
			callback: [:value | self check: value. self check2: value].
		html text: 'Check me'.
		html checkbox
			onChange: (html jQuery ajax serializeThisWithHidden);
			value: self isChecked2;	
			callback: [:value | self check2: value. self check: value not].
		html text: 'Check me 2'.
	]

So what's the best strategy to update the checkboxes reflecting the
internal state?
