title: CCMenuItemLable don't run block or selector
body: <p>I'm trying to use CCMenuItemLabel, but when I press it nothing happens. 
  I also have menu item with sprite that works perfectly with about the same code.</p>
  
  <p>Any idea?</p>
  
  <pre><code>CCMenuItemLabel *miLabel = [CCMenuItemLabel itemWithLabel:tmpLabel target:self selector:@selector(doSomethingTest)];
  
  miLabel.tag = tmpTag++;
  __block NSString *actionName = [menuItemData objectForKey:kActionName];
  [miLabel setBlock:^(id sender) {
        ASLog2Debug(@"[Test]");
        [self handlePressForMenuItemWithActionName:actionName];
  
  }];
  </code></pre>
