title: jqGrid: Why aren't the events that I defined for a grid edit firing?
body: <p>I'm doing in-line edits on a grid, but can't seem to get any events to fire that would be tied to that edit.</p>
  
  <p>Here I have afterSubmit: and I want it to fire after the user has edited the Quantity field in the grid, but it never fires.</p>
  
  <pre><code>$('#tblLines').jqGrid({
          url: createUrl('/CRA/GetLines/'),
          editurl: '/CRA/EditModifyLine',
          emptyrecords: '',
          datatype: 'json',
          mtype: 'GET',
          colNames: ['Group', 'Description', 'Quantity'],
          colModel: [
        { name: 'Group', index: 'Group', width: 100, align: 'left' },
        { name: 'Description', index: 'Description', width: 400, align: 'left' },
        { name: 'Quantity', index: 'Quantity', width: 150, align: 'left', editable: true },
          pager: jQuery('#pgrLines'),
          rowNum: 10,
          rowList: [5, 10, 20, 50],
          sortname: 'Group',
          sortorder: "desc",
          viewrecords: true,
          caption: 'Core Group Lines',
          onSelectRow: function(id) {
              $('#tblCoreGroupLines').editRow(id, true);
              lastsel = id;
          },
          afterSubmit: function(response, postdata) {
              alert('got here');
          },
          postData: { craId: $('#CraId').val() }
      });
  </code></pre>
  
  <p>I've tried defining the events lower as part of a navControl, but that doesn't work either. The in-line edit works fine -- the POST succeeds and the result comes back, it just never hits the events that should be tied to it. I've tried all the events that would tie to the changing of the Quantity field, but none of them work.</p>
  
  <p>Have I defined the event in the correct place? Am I missing a property on the grid or something?</p>
