How to get deviceready event in Cordova/ionic?

I'm building an app using the ionic framework (which is built on top of Cordova) and I now want to catch the deviceready event. Around the internet I've found various methods of doing this. I've tried the following three ways:

document.addEventListener('deviceready', function () {console.log('IT IS READY!');});

$ionicPlatform.ready(function () {console.log('IT IS READY!');});

window.ionic.Platform.ready(function() {console.log('IT IS READY!');});

but none of these work. I surrounded these lines with log statements, and all code before AND after it is executed, so it doesn't halt there. I'm trying this on a physical Android device (haven't tried iOS yet).

I don't get any error messages. The only possibly relevant log I get in my terminal is one referring to the keyboard which cannot be read:

I/chromium(25678): [INFO:CONSOLE(20)] "Uncaught TypeError: Cannot read property 'Keyboard' of undefined", source: file:///android_asset/www/js/app.js (20)

Does anybody know why this doesn't work and how I can solve it? All tips are welcome!

The default 'blank' Ionic template has this code in app.js and it works perfectly.

angular.module('starter', ['ionic'])
.run(function($ionicPlatform) {

  $ionicPlatform.ready(function() {

    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if(window.cordova && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }

  });
})

Maybe you are placing your $ionicPlatform.ready(function () {}); in the wrong place.
