Execute a function at the end of the last effect of a Jquery.queue
<p>&nbsp;&nbsp;I would like to use fx and functions
I have a animation, and i would like to, at the end of the queue, do an ajax call.  <br/>
&nbsp;&nbsp;I can't seem to make it work...  <br/>
&nbsp;&nbsp;I have absolutely no idea how to procede... </p>

<p>that would a very very  rough example, but</p>

<pre><code>$('#dvHeader').queue(function() {
  $('#dvLeftContent').slideDown(2000);
  $('#dvRightContent').animate({ backgroundColor: '#c71717' }, 2500)
  callAjax();
}
</code></pre>

<p>&nbsp;&nbsp;This code calls the callAjax function way before the last effect starts, in fact, almost as the first one is called.<br/>

<i>&nbsp;&nbsp;The real case is a little more complex, i cannot use a callback of the animate effect, per example. I would like to know when the queue ends the last effect, or something like it.</i><br/>
&nbsp;&nbsp;How could I make that call to be triggered at the end of the last animation?</p>
