title: Access function in a child with Flash CC and Createjs
body: <p>Hi all I have a problem with my program on flash cc with createjs. I have a movie clip with instances name "target1". Inside it, I have a function called <code>triggerTarget()</code>, but when I'm trying to accessing this function on movieclip "target1", it always showing <code>TypeError:target1.triggerTarget is not a function</code>. Here is my code :</p>
  
  <pre><code>var that=this;
  that['target1'].triggerTarget();
  </code></pre>
  
  <p>I'm also trying this code.</p>
  
  <pre><code>exportRoot['target1'].triggerTarget();
  </code></pre>
  
  <p>I can access that movieclip object, but I can not reach the function inside it, can anyone help me with this?</p>
