title: JQuery $.getJSON runs the first time, then never again
body: <p>I have a button click function that is to run a  $.getJSON when the button is clicked. It gets some values from a controller posts those to some form fields and opens a modal that contains the form.
  The first time I click the button it runs the  $.getJSON posts the values and opens the modal just fine.
  when i close the modal and click the button again. It just opens the modal and the values are the old values. It doesn't run the  $.getJSON again. I know it doesn't also because I put a break point in the controller. It hits the break point that first time. But won't go into the controller the other times until I completely reload the page.</p>
  
  <p>here is my button click script</p>
  
  <pre><code>   $('[id^=edit]').button().click(function () {
      var selected = $(this).val();
      var arr = selected.split(',');
      var item = arr[0];
      var parent = arr[1];
      $("#itemspan").text(parent);
      $("#parentspan").text(item);
      $("#partno")[0].value = item;
      $("#parent")[0].value = parent;
      var url = $("#itemdetailsjsonurl").attr("href");
      var fullurl = url + '/' + item + '/' + parent;
      $.getJSON(fullurl, null, function (data) {
          $("#qty")[0].value = data.qty;
          $("#startdate")[0].value = data.sdate;
          $("#enddate")[0].value = data.edate;
          $("#notes")[0].value = data.memo;
      });
  
      $("#edtbomitem").dialog('open');
  });
  </code></pre>
  
  <p>any ideas why?</p>
