Failed to setup OneSignal in Ionic2

Hi,

I use OneSignal for push notification, as their instruction I added code as following:

// Call any initial plugins when ready
platform.ready().then(() => {

StatusBar.styleDefault();
Splashscreen.hide();

alert(“Before init”);

// Enable to debug issues.
window[“plugins”].OneSignal.setLogLevel({logLevel: 4, visualLevel: 4});

var notificationOpenedCallback = function(jsonData) {
console.log('didReceiveRemoteNotificationCallBack: ’ + JSON.stringify(jsonData));
};

window[“plugins”].OneSignal.init(
“2aca2c26-790b-4f00-b5a1-56130206d6e2”,
{googleProjectNumber: “529504018999”, autoRegister: true},
notificationOpenedCallback
);

// Show an alert box if a notification comes in when the user is in your app.
window[“plugins”].OneSignal.enableInAppAlertNotification(true);

alert(“After init”);

});

It doesn’t work (no subscriber in dashboard). When I check source compiled in JS file (app.bundle.js), I got this below:
// Call any initial plugins when ready
platform.ready().then(function () {
ionic_native_1.StatusBar.styleDefault();
ionic_native_1.Splashscreen.hide();
});

Perhaps you guys can help me to explain this symptom and help me to get over this integration problem.
Many thanks!

UPDATED!

I’ve successfully integrate this awesome OneSignal to Ionic2, after reinstall ionic@beta.

Hello, you can share how to integrate the OneSignal with Ionic, I have been able to implement Ionic Push, however need OneSignal (Sorry for my English is not my native language)
