title: How to cause a postback using jquery autocomplete on option select?
body: <p><a href="http://jsfiddle.net/g23vrfoe/1/" rel="nofollow"><h1>TEST AREA</h1></a></p>
  
  <p>I have created a simple jquery-ui autocomplete demo.</p>
  
  <p><strong>QUESTION</strong></p>
  
  <p>How can I cause a postback to occur when an option is selected from the list?</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;select id="ddl"&gt;&lt;/select&gt;
  &lt;input id="field" type="text"&gt;&lt;/input&gt;
  </code></pre>
  
  <p><strong>JQUERY</strong></p>
  
  <pre><code>$("#field").autocomplete({
      select: function(event, ui) {
          __doPostBack("#ddl", ""); //Postback will not occur here?
      }
  });
  </code></pre>
  
  <p><strong>NOTES</strong></p>
  
  <p>The rest of the code in this demo is not required, it is simply there to show that an option is being successfully selected. </p>
  
  <p>I can't see what is preventing the postback from occuring. I simply want a postback to occur when the user picks any option from the list generated by the autocomplete.</p>
