I implemented an example : https://github.com/aliok/diff-sync-ionic

Youtube screencast : https://youtu.be/MmSd_5pFP3E

I basically ported https://github.com/aerogear/aerogear-js-cookbook/tree/master/diff-sync-ember and added some more features (adding new hobby, ordering hobbies, deleting hobbies)

See the project page for more information.

If you people liked it, I can fork https://github.com/aerogear/aerogear-js-cookbook/, put the code there under new folder diff-sync-ionic and create a pull request.
