Pointer reference?

Question

Hi, I'm pretty new to iPhone application development and I'm doing well so far. But at one point my App doesn't do what it is intend for... It's a tableview based app and i'm pushing a new controller onto the stack to get some Userinput, but when the controller is popped again the data is somehow gone. Perhaps I've missunderstood something with the pointers??

rootviewcontroller.m:

edit = [fields objectAtIndex: indexPath.row];
listView.element = edit;
[self.navigationController pushViewController: listView animated:YES];

ListView.m:

element.value = [list objectAtIndex: indexPath.row];
[self.navigationController popViewControllerAnimated:YES];

so what am I doing wrong?

Thanks for your help

edit:

the value field is shown in the tableview with the cellForRowAtIndexPath method:

if (indexPath.section == 0) {
UILabel *title = (UILabel*) [cell viewWithTag:1];
UILabel *detail = (UILabel*) [cell viewWithTag:2];
ListElement *l = [fields objectAtIndex: indexPath.row];
title.text = l.name;
detail.text = l.value;

If the data is "gone" means "it's not shown after returning to root view" it can probably be fixed by

- (void) viewWillAppear:(BOOL)animated
{
   [self.tableView reloadData];
}

put into RootViewController.
