UISearchBar member not called when using UINavigationBar as header?

Question

I have a UITableViewController which I specified as UISearchBarDelegate. Until now, I programmatically added a UISearchBar to the headerView of the table, and there were no problems.

I ended up shielding the property, so I decided to kill my usual UINavigationController header (which was the text) and added the following code, moving my SearchBar from the table to the UINavigationBar:

// (Called in viewDidLoad)
// Programmatically make UISearchBar
UISearchBar *tmpSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,45)];
tmpSearchBar.delegate = self;
tmpSearchBar.showsCancelButton = YES;
tmpSearchBar.autocorrectionType = UITextAutocorrectionTypeNo;
tmpSearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
[self set_searchBar:tmpSearchBar];
[tmpSearchBar release];
self.navigationItem.titleView = [self _searchBar];

This code works as expected - my UINavigationBar is now a UISearchBar. However, my delegation method:

/** Only show the cancel button when the keyboard is displayed */
- (void) searchBarDidBeginEditing:(UISearchBar*) lclSearchBar
{
  lclSearchBar.showsCancelButton = YES;
}

... is no longer called. I stopped and I confirmed that the UISearchBar delegate is indeed the view controller itself. Oddly enough, this delegate method is still called just fine:

/** Run the search and resign the keyboard */
- (void) searchBarSearchButtonClicked:(UISearchBar *)lclSearchBar
{
  _deepSearchRan = NO;
  [self runSearchForString:[[self _searchBar] text] isSlowSearch:NO];
  [lclSearchBar resignFirstResponder];
}

, UINavigationBar ? ?
