ios - Why is -didDeselectRowAtIndexPath not being called?

I created a fresh project (Xcode 4, Master-Detail application) just to see if I'm doing something wrong, but I still have the same problem. I want to call -reloadData when the user deselects a cell, so this is my code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    NSLog(@"%s", __PRETTY_FUNCTION__);
}

-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"%s", __PRETTY_FUNCTION__);
    [tableView reloadData];
}

-(NSIndexPath *)tableView:(UITableView *)tableView willDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"%s", __PRETTY_FUNCTION__);
    return indexPath;
}

The problem is that didDeselectRowAtIndexPath and willDeselectRowAtIndexPath don't seem to be called. Is this the expected behavior? The docs for tableView:didDeselectRowAtIndexPath: state

Tells the delegate that the specified row is now deselected.

so I guess that it should work as I thought.

If you call deselectRowAtIndexPath:animated:, the delegate methods tableView:willDeselectRowAtIndexPath: and tableView:didDeselectRowAtIndexPath: message are not sent.
