Title: Run slide change callbacks after modifying the page

If the callback is invoked before modifying the page, one can't tell
which is the current slide, because it actually hasn't been changed in
the page yet. It's more useful if the "previous slide" ou "next slide"
events are dispatched after the page is modified.
