Core Data: deleteObject does not trigger Table Update - uitableview

Question

I have an UITableView with menu items, and when the menu changes the server pushes the new list to the devices. The table view which shows the list automatically updates when I add menu items or change them when the changes are committed.
However, when I delete an object then this is not reflected in the list (and neither when I change the order, which means a 'level' field of the object).
These changes only show after I completely close (kill) the App and restart.
Is there a simple reason why the update is not triggered?
for(DOMenuItem* item in _oldMenuIdList){
[[self managedObjectContext] deleteObject:item];
}
NSError *error;
if(![[self managedObjectContext] save:&error]) {
NSLog(#"Error!");
}

[Edit 2:]
In the UIViewController:
- (void)viewDidLoad
{
iDomsAppDelegate *delegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate];
// Get the menu's
_objects = [[[DOMenuItemsController alloc] init:[delegate managedObjectContext]] findChildrenOfMenu:(DOMenuItem*) _parentMenu];
[_objects setDelegate:self];
