Keyboard will/did hide/show events should be passed to JavaScript

In order to resolve the issues iOS 7 creates with the keyboard shrinking the view, our project needs the KeyboardWillShow, KeyboardDidShow, KeyboardWillHide and KeyboardDidHide native events to be raised by the keyboard plugin as JavaScript events, so that we can show/hide some HTML elements.

Would it be possible to add observers for the "Will" events as well as the "Did" events, and then make all four observers execute some JavaScript to trigger events in the DOM.
