Using Events

Since all the Ionic events can be used the same way, we will show you how to use the on-touch event and you can just apply the same principles to the other events. To start with, we will create a button and assign an on-touch event, which will call the onTouchFunction().

<button on-touch = "onTouchFunction()" class="button">Test</button>

Then we will create that function in our controller scope.

$scope.onTouchFunction = function() {
   // Do something...
}

Now, when touch event occurs the onTouchFunction() will be called.
