title: Cocos2d-x how to invoke functions right after Spawn action
body: <p>i have simple animation that scale and move over time thogeter the only way i found to do it 
  is using Spawn action
  the problem is that i like to invoke function action right after the Spawn action done . 
  and using it in the Spawn action will trigger the Func action all the time .. </p>
  
  <pre><code>auto action = Spawn::create(
          MoveTo::create( 0.5, Vec2(spriteW,v.y/2)),
          ScaleTo::create(0.5f,1.0f),      
          nullptr);
  
      pBonusContainer-&gt;runAction(action);
  </code></pre>
  
  <p>i need to invoke the </p>
  
  <pre><code>CallFunc::create( CC_CALLBACK_0(FontContainer::removeSignCallback,this,pToolsToRemove))
  </code></pre>
  
  <p>right after MoveTo and ScaleTo done its thing with Spawn</p>
