Missing keyboard/input event on BACKSPACE

[reppners]

Hey there,

this keyboard works really nice in one of our applications but we are missing one thing:

When backspace is hit, there is no keyboard events (keydown, keyup, keypress) or a change event on the input element which makes it hard to detect changes in a underlying model value. We are using AngularJS and this breaks the databinding and forces to check the value of the input field on intervals. I would do the change and submit a pull-request if you welcome contributions.

Can you please try again? Did some changes in the keyboard events.
