title: set value to jquery autocomplete combobox
body: <p>I am using <a href="http://jqueryui.com/demos/autocomplete/#combobox" rel="noreferrer">jquery autocomplete combobox</a>
  and everything is ok. But I also want to set specific value through JavaScript like <code>$("#value").val("somevalue")</code> and it set to select element, but no changes in input element with autocomplete.</p>
  
  <p>Of course, I can select this input and set value directly, but is it some other ways to do that? I try set bind to <code>this.element</code> like <code>this.element.bind("change", function(){alert(1)})</code> but it was no effects. And I don't know why. </p>
  
  <p><strong>Edit</strong></p>
  
  <p>I found a workaround for this case. But I don't like it. I have added the following code to _create function for ui.combobox</p>
  
  <pre><code>this.element.bind("change", function() {  
      input.val( $(select).find("option:selected").text());  
  });
  </code></pre>
  
  <p>And when I need to change the value I can use <code>$("#selector").val("specificvalue").trigger("change");</code></p>
