Basically you are not redirecting from one function to other, here you are calling a method's functionality in your code. Its like Ajax way, no url change but content can be changed.

Code:

redirect('page/step2');

I try and app writes:
Call to undefined function redirect()
What wrong?

just added helper and it works.
