Ionic - How to execute a function only after an update has been made

Does anyone know how to execute a function only after an update using Ionic Framework?

The situation is as follow: My app is already on the store. I want to make an update. After that update I want a function to execute when the user opens the app for the first time after the update. How can I achieve this?

Thank you!

Is this what you're after? Probably best to put it into your app's run() function:

$ionicPlatform.ready(function() {
    if (!window.localStorage.hasOwnProperty('functionExecuted')){
        //Place your code here

        window.localStorage['functionExecuted'] = true;
    } 
});
