On Open app First screen not executing the controller

Hey everyone

Im quite new to all this mobile develop and angular at the same time.

I have been following this tutorial:

when i just run the app

ionic serve

everything is loaded just fine.
But when i run it on my android device, it will not execute the controller in the first view unless i tap on a link to another view and jump back on the first view.

anyone know why and how to fix this.
