Subject: fix(ngModel): use keydown/change events on IE9 instead of input

On IE9 the input event is not fired when backspace or delete key are pressed or when
cut is performed. This makes listening on the input event unreliable and therefore
it's better for us to just use keydown/change events instead.

Closes #879
