title: jQuery datepicker() - defaulting to yyyy/mm/dd
body: <p>When I select a date on the datepicker, I need it
  to default to yyyy/mm/dd</p>
  
  <p>When I do the following:</p>
  
  <pre><code>     $(id).datepicker("option", "dateFormat", 'yyyy/mm/dd');
  </code></pre>
  
  <p>and select a field, the datepicker does not even come up. </p>
  
  <p>Is there anything wrong with what I have above? </p>
  
  <p>obviously </p>
  
  <pre><code>     $(id).datepicker(); 
  </code></pre>
  
  <p>work but it does not form that date the way I like it " yyyy/mm/dd</p>
