title: Angular jsFiddle example doesn't work
body: <p>I can't understand why <a href="http://jsfiddle.net/zishe/8HxjM/60/" rel="nofollow">this</a> doesn't work. The error is</p>
  
  <pre><code>Error: Argument 'TodoCtrl' is not a function, got undefined
  </code></pre>
  
  <p>I guess the issue is simple, but I can't solve it. In general, I want to change the text periodically. </p>
