Title: had wrong callback string in the js layer

the callback event string in the javascript layer was :
requestVibrationCallbackResult

but it required this string to match from C++
vibration_requestCallbackResult

hidaya helped me find that out. I think I had made the change locally at some point so thats why the test app had worked for me. This change should resolve the issue and all a callback function to fired when the vibration function returns.
