"ESC" event keycode not detected in document.keydown listener while exiting fullscreen mode

Question

I have a code to fire on exiting full screen mode.
Therefore, i bind it to :
# (window.document).keyup(function(e) {
# if(e.keyCode === 27 ) {
# // do something //
Now, When i am in fullscreen mode,
1. When i press "ESC", Fullscreen mode exits but my function does not gets fired.
2. When i press "ESC" after fullscreen mode have exited, My function gets fired.
That means "ESC" event was not propagated to code when browser was in fullscreen mode.
( * This works correctly in chrome )
3. This is bit too much too ask, but can i bind browser's exit full screen button which appears at the top ??

If you are using HTML5, I think the way to do is to bind with the fullscreen APIs that are still in''progress''. You could try these two links to see if that helps you

You could create an event listener for the document.cancelFullScreen() and then see if that helps.
Any specific reason why you want to bind to the button and not to the event?
