title: Push notification on click event does not work when app is in background Ionic 3
body: <ol>
  <li>I am using <strong>phonegap-plugin-push</strong> for push notification in Ionic 3</li>
  <li>I received notification, but while clicking on notification I didn't get any response.</li>
  <li><p>I want to redirect to a selected page while clicking on notification. Below is my code.</p>
  
  <pre><code>public pushNotification(){
    const options: PushOptions = {
      android: {
        senderID: 'xxxxxxxx',
        icon: 'icon',
        sound: true,
        vibrate: true
      },
      ios: {
        alert: true,
        badge: true,
        sound: true,
      }
    };
  
    let isNotifyAvailable: boolean = false;
    const pushObject: PushObject = this.push.init(options);
    let me = this;
    pushObject.on('notification').subscribe((notification: any) =&gt; {
      console.log('Received a notification', notification);
      if (notification.additionalData.foreground) {
        me.utilService.showToastMsg("success", notification.message);
      } else {
            this.navCtrl.setRoot(NotificationList);
      }
    });
  }
  </code></pre></li>
  <li><p>In the backend I am using <strong>FCM</strong> notification in Python.</p></li>
  </ol>
  
  <p>How can I redirect in selected page when click on Notification?</p>
