Dynamic reloading app

I have a dynamic app that loads most of the js/html/css from my server.

However, on Android, with Ionic/Cordova, when changing my.com/app.js which is pulled in index.html,

it seems index.html itself doesn’t bother re-loading the index.html every time (even after app restart)

How should I force index.html or otherwise get Ionic/AngularJS/JS to use latest from my.com/my.js — eg, controller.js?

How might I best reload the latest versions of the app, upon, say, resume/restart?
