WebUIDelegate methods are not called

For some reason, the following webview user interface delegation methods are never called. Tried opening, clicking, interacting with the webview to trigger delegate calls, and nothing works.

- (void)webViewFocus:(WebView *)sender {
    NSLog(@"focusing %@", sender);
}

- (void)webViewUnfocus:(WebView *)sender {
    NSLog(@"unfocusing %@", sender);
}

- (BOOL)webViewIsStatusBarVisible:(WebView *)sender {
    return YES;
}

- (void)webView:(WebView *)sender setStatusBarVisible:(BOOL)visible {
    NSLog(@"%@  %d", sender, visible);
}

I made sure that the delegate is connected correctly and can confirm that when the user wants to open a new window, the - (WebView *)webView:(WebView *)sender createWebViewWithRequest:(NSURLRequest *)requestWebUIDelegate method is called correctly. Any ideas?
