title: Set title Cakephp 2.x
body: <p>I am trying to change the title of a page. 
  The default.ctp view has the following code:</p>
  
  <pre><code>&lt;title&gt;
      &lt;?php echo $this-&gt;fetch('title'); ?&gt;
       - Welcome
  &lt;/title&gt;
  </code></pre>
  
  <p>I'm trying to use the following code in the controller of the page:</p>
  
  <pre><code>$title = 'Overview';
  $this-&gt;set('title');
  </code></pre>
  
  <p>But unfortunately I do not see see 'Overview - Welcome', but only the name of the function of the controller followed by ' - Welcome'.
  Can anyone help me to find the problem why it is not working?</p>
