title: Yii CGridView - set default afterAjaxUpdate callback
body: <p>does somebody know a possibilty to set a default function in CGridView, which will run on all grids on the page after every AJAX update?
  I use the CGridView on many pages, and I don't want to specify this function for each grid separatly.
  I need this because I use <a href="https://github.com/fnagel/jquery-ui" rel="nofollow">jQuery selectmenu</a> for my filter dropdowns, and after the AJAX reload, they need to be inicialized again.</p>
  
  <pre><code>'afterAjaxUpdate' =&gt; "function(id,data){$('select').selectmenu()}";
  </code></pre>
