title: jQuery combobox setting default value after creation
body: <p>I'm having a difficulty using the jQuery combobox widget as mentioned <a href="http://jqueryui.com/demos/autocomplete/#combobox" rel="nofollow noreferrer">here</a>:</p>
  
  <p>I'm using jQuery to load the options for the select using ajax, which means that upon creation of the combobox, there are no options in it. When I get the values from the ajax call, I set the first option to be be selected. This works fine for the underlying select, but not for the input-field which jQuery combobox has added. </p>
  
  <p>I've seen the solution <a href="https://stackoverflow.com/questions/2749721/how-do-set-a-default-value-with-jquery-autocomplete-combobox">here</a> but this will not work if the options are added after _create is called(also, it is kinda outdated since the widget by default handles this). </p>
  
  <p>As far as I can tell, there are no relationsship between the underlying combobox and the input-field that makes the one update the other. Or am i wrong here?</p>
