title: Add html element inside of form element using cake php form helper
body: <p>I am trying to create a simple html output that looks like this </p>
  
  <pre><code>&lt;button class="searchbutton" id="search_button" type="submit"&gt;--&gt;
        &lt;i class="icon-search"&gt;&lt;/i&gt; Search&lt;/button&gt;
  </code></pre>
  
  <p>with Cake php's form helper, i cant figure out why the 'after' attribute doesn't add the inner <code>&lt;i&gt; &lt;/i&gt;</code> html element.</p>
  
  <p>This is what i have tried.</p>
  
  <pre><code>  echo $this-&gt;Form-&gt;button('Search', array('type' =&gt; 'submit','id' =&gt; 'search_button','class' =&gt; 'searchbutton',
          'after' =&gt; "&lt;i class='icon-search'&gt;&lt;/i&gt;"));
  </code></pre>
