Input field transition on iOS vs. Android

Hi there

I am working on the registration screen as in http://plnkr.co/edit/wfVWIpRt6oxkSM5W0Qjg?p=preview. I have a questions about implementing field transition.

  1. On Android there is Next button, how can I implement ‘tabbing’ to next field for iOS?
  2. I have a textarea field on the screen, the Go button disappears for this field. Can the behavior be changed, like with ui-keypress="{13:‘profileForm.submit()’}"?

Thank you very much for looking into this,
Irena
