This way you can control events when player is loaded and changes state (playing, pause, stopped, …).

Note: To test on real device, I’ve created a blank ionic 1.0 project with:
ionic start youtubeTest blank
ionic platform add android
ionic plugin add cordova-plugin-whitelist (this is needed to enable network calls)
pasted the code from pen and then:
ionic run android
