app.initialize();

I have complete following procedure:

1. added above code in index.js file
2. add this line in in config.xml
3. add this line "<script type="text/javascript" src="cordova.js"></script>" in index.html

but this function "push.on('registration', function(data) {" never get call back and never get registrationId. :(
