Anti-pop BB10 resets form data

I use bbui.js and ripple 0.9.10 tests I am new to bbui.js so I learn that I will.

Here's my problem.  I have an application that uses multiple screens.  From the main screen, I push a screen on top that allows the user put in some data.  If the user needs more information they can navigate to another screen that is pushed up.  Now, we have the main screen, a second screen for entry and a third of the screen.  This third screen the user gets what they need, the on-screen and ends at their entrance on the second screen.  Problem is, when the third screen is skipped, any input the user set the second screen before you navigate to the third screen disappeared.  Now I don't know if it's a bug or expected behavior.  If this is the expected behavior is there a people model typical use so the user when the user navigates to other screens of entry on a screen?

Not even necessary... See examples of code at the beginning of my index.html:
