Hi!
there is something wrong in the documentation.
The description of the resize-event is definitely wrong, it’s the same as of the resume-event.
There already is an issue for that here: https://github.com/ionic-team/ionic-site/issues/1103
But thanks for noticing and reporting anyway!
Please fix this, I needed some time to figure out the issue 
so that nobody else has to wonder why his code wont work.
