Cordova/Ionic on Android - How to force index.html to pull latest src from my.com/app.com

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