android - Firebase push notifications update DB

Question

I'm trying to send some data to my users via the new Firebase push notifications service.

I'm adding some "key-value" custom data items with 'Message text' - "dbupdate" to detect if it's an update message or a normal push notification that I want to show my users.

In my receiver I check i there is custom data and run the update, if true. If this isn't the case, I show a normal notification with the text message.

It works only when my application opened. If the application is closed, the notification is shown anyway, and my if check doesn't even running,

some code:

public class PushMessageService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Map<String,String> data = remoteMessage.getData();
        String link = data.get("link");
        String name = data.get("name");
        if (link!=null) {
            Log.d("link",link);
            Log.d("name",name);
            UpdateHelper.Go(this, link, name);
        }
        else {
            NotificationCompat.Builder mBuilder =
                    new NotificationCompat.Builder(this)
                            .setSmallIcon(R.drawable.ic_shop_white_24dp)
                            .setAutoCancel(true)
                    .setContentTitle(remoteMessage.getNotification().getTitle())
                   .setContentText(remoteMessage.getNotification().getBody());
            NotificationManager mNotificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            mNotificationManager.notify(5, mBuilder.build());
        }
    }
}

Why is that so? What can I do to run my code even when the application closed?
