Question about resetting views

Hi everyone,
Just a question regarding views. It might be that my depth of knowledge of how iPad programming is supposed to work is lacking. I'm developing an application that's essentially a test, where users step through multiple views and input information (switches, buttons, data) before saving it all at the end and shipping it off. The issue I am having is if the user were to step back through the test and then re-move forward, iPad will not store the previously assigned information (i.e. it wipes the view back to default). Is there a way to modify this behaviour? I'd like to ensure that no matter where the user goes within the test, the information added will remain there. Thank you in advance.
