My JS Code look like : I am writing below code inside device.ready event
document.addEventListener("urbanairship.registration", function (event) {
alert("Inside");
if (event.error) {
alert('there was an error registering for push notifications');
} else {
alert("Registered with ID: " + event.pushID);
}
}, false);
document.addEventListener("urbanairship.push", function (event) {
alert("Incoming push: " + event.message);
}, false);
