Title: Fix double click bubbling for checobox

'Cause of http://www.w3.org/TR/html5/forms.html#labeled-control checkbox clicks bubbles twice. We used to have check inside click's handler, but events bubbling anyway. It's not obvious when click fires twice on some element under the checkbox and can broke something.

When user clicks on checkbox (input itself or label) change event will be fired on input anyway and it will be once. So it's better to subscribe our handler on input change.
