MobileFirst and Ionic Push notification callback - ibm-mobilefirst

Question

I have an Ionic project and I added a push notification callback handler as explained in official documentation (my expectation is to have some alert when inside the app and a notification arrive), but it is never invoked.
WL.Client.Push.registerEventSourceCallback(
"myPush",
"PushAdapter",
"PushEventSource",
pushNotificationReceived);
Here the question is where I have to place the pushNotificationReceived function to be called ? I try in index.js and inside the controller as a function, but I do not have success.
Thank for help

Answer 1

Have you reviewed the sample application for push notifications?.
The sample demonstrates implementation of push notifications APIs. https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-7-1/foundation/notifications/push-notifications-overview/push-notifications-in-hybrid-applications/event-source-notifications-in-hybrid-applications/
See the supplied main.js file: https://github.com/MobileFirst-Platform-Developer-Center/EventSourceNotifications/blob/release71/apps/HybridEventSource/common/js/main.js

You have to include callback function in ionic inside the app.js file after "Successfully connected with mobile first server".
WLAuthorizationManager.obtainAccessToken().then(
function (response) {
//alert("successfully obtained a token from the server");
MFPPush.initialize (
function(successResponse) {
//alert("Successfully intialized");
MFPPush.registerNotificationsCallback(notificationReceived);
},
function(failureResponse) {
console.log("Failed to initialize");
}
);
MFPPush.isPushSupported (
function(successResponse) {
//alert("Push Supported: " + successResponse);
},
function(failureResponse) {
console.log("Failed to get push support status");
}
);
MFPPush.registerDevice(
function(successResponse) {
//alert("Successfully registered");
},
function(failureResponse) {
console.log("Failed to register");
}
);
function notificationReceived(message) {
alert(JSON.stringify(message.alert));
}
},
function(response) {
//alert("res"+JSON.stringify(response));
console.log("Unable to obtain a token from the server: " + JSON.stringify(response));
if(JSON.stringify(response.status) == 403){
console.log("The Application is disabled on this Device");
ionic.Platform.exitApp();
}
}
);
