title: Adding events to device calendar using Ionic framework
body: <p>I'm creating a cross platform mobile app using Ionic framework and AngularJS
  In this app I need to get a date string and add it to the device's native calendar, is there a way to do so using only Ionic and AngularJS?
  and if there's no way to do so, can you tell me if there's a way doing so without them?
  Thank You !</p>
