How to dismiss a popover with a navigation controller? - ios

Question

I have an app which is divided in four views, when I tap a view the app shows a popover and that popover has a navigation controller. I can navigate between view and the data is shows correctly. But when I am in the last view and I tap a row, the popover don't dismiss (I want in didSelectRowAtIndexPath).
How could do it?
I tried in this way, I created a method that dismiss the popover and I call this method en didSelectRowAtIndexPath, but did not works.
This is the method in the main ViewController
-(IBAction)mostrarTabla:(id)sender
{
// Popover that shows the table
UIPopoverController *popover;
// RootViewController is the first view
RootViewController *rootViewController = [[RootViewController alloc] init];
// With a nav bar
UINavigationController *navBar = [[UINavigationController alloc] initWithRootViewController:rootViewController];
[rootViewController release];
// Popover customitation
navBar.contentSizeForViewInPopover = CGSizeMake(20.0f, 20.0f);
popover = [[UIPopoverController alloc] initWithContentViewController:navBar];
[navBar release];
popover.delegate = self;
popover.popoverContentSize = CGSizeMake(320.0f, 832.0f);
// PopOver is shows in the view 1
[popover presentPopoverFromRect:CGRectMake(100.0f, 10.0f, 20.0f, 20.0f) inView:_view1 permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
I create a method in this View Controller
-(void)hidePopover
{
[self.popOver dismissPopoverAnimated:YES];
}
And in the last view I used the method but did not works
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ViewController *grafica = [[ViewController alloc] init];
self.indicadorId = [[self.arrayId objectAtIndex:indexPath.row] integerValue];
DataIndicador *datos =[[DataIndicador alloc] init];
datos.idIndicador = self.indicadorId;
[datos release];
[grafica hidePopover];
}
In the last view I want that the popover returns to its view and shows the data (a chart)
Thanks

The grafica instant of the ViewController is not the same as the whatever instant of VieController that was originally presented the popover.
