How to customize fullscreen button in google maps?

Question

Google

I need to customize the map control buttons. I did the Zoom in and Zoom out, now I need to customize the Expand button to full screen.
I need a method that will reset the control from the standard fullscreen button to the one I created.
Here's what I used for the zoomIn/zoomOut buttons:

google.maps.event.addDomListener(controlUIzoomIn, 'click', function() {
    map.setZoom(map.getZoom()+1)
});
google.maps.event.addDomListener(controlUIzoomOut, 'click', function() {
    map.setZoom(map.getZoom()-1)
});
