title: jqGrid custom edittype (radio button column) custom element not firing set event on edit
body: <p>I have a jqGrid which needs to have radio buttons in a column of a row while editing.
  Following is my code:</p>
  
  <pre><code>function BindPreclosingDocs(response) {
      var previouslyselectedRow;
      var preclosingtable = $('#preclosing');
      preclosingtable.jqGrid({
          datatype: 'jsonstring',
          datastr: JSON.stringify(response.ServiceModel),
          colNames: ['', 'Documents Received', 'Comments', 'SubDocument', 'NA'],
          colModel: [
          { name: 'Documents', index: 'Documents', align: 'left', sortable: false, editable: false, width: 240 },
          { name: 'DocsReceived', index: 'DocsReceived', align: 'center', sortable: false, editable: true, edittype: 'checkbox', editoptions: { value: "True:False" }, formatter: "checkbox", width: 140 },
          { name: 'Comments', index: 'Comments', align: 'center', sortable: false, editable: true, edittype: "textarea", editoptions: { rows: "3", cols: "16" }, width: 180 },
          { name: 'SubDocument', index: 'SubDocument', editable: false, width: 1 },
          { name: 'NA', index: 'NA', editable: true, formatter: 'dynamicText', width: 150, edittype: 'custom', editoptions: { custom_element: radioelem, custom_value: radiovalue} }
          ],
          rowNum: response.ServiceModel.PreClosing.length,
          pager: '#preclosingpagerdiv',
          viewrecords: true,
          sortorder: "asc",
          sortname: 'Documents',
          jsonReader: {
              root: "PreClosing",
              repeatitems: false,
              id: 'ConfigId'
          },
          shrinkToFit: false,
          height: 'auto',
          grouping: true,
          groupingView: {
              groupField: ['SubDocument'],
              groupColumnShow: [false],
              plusicon: 'ui-icon-circle-triangle-s',
              minusicon: 'ui-icon-circle-triangle-n'
          },
          loadComplete: function () {
              HideGroupHeaders(this);                
          },
          onSelectRow: function (id) {
              preclosingtable.jqGrid('saveRow', previouslyselectedRow, false, 'clientArray');
              previouslyselectedRow = SetJQGridRowEdit(id, previouslyselectedRow, preclosingtable);
          }
      });
      preclosingtable.setGridWidth('710');
  };
  
  
  //RowSelect 
  function SetJQGridRowEdit(id, previousid, grid) {
      if (id &amp;&amp; id !== previousid) {
          grid.jqGrid('restoreRow', previousid);
          grid.jqGrid('editRow', id, true);
          previousid = id;
          return previousid;
      }
  };
  
  //Build radio button
  function radioelem(value, options) {
      var receivedradio = '&lt;input type="radio" name="receivednaradio" value="R"';
      var breakline = '/&gt;Received&lt;br&gt;';
      var naradio = '&lt;input type="radio" name="receivednaradio" value="N"';
      var endnaradio = '/&gt;NA&lt;br&gt;';
      if (value == 'Received') {
          var radiohtml = receivedradio + ' checked="checked"' + breakline + naradio + endnaradio;
          return radiohtml;
      }
      else if (value == 'NA') {
          var radiohtml = receivedradio + breakline + naradio + ' checked="checked"' + endnaradio;
          return radiohtml;
      }
      else {
          return receivedradio + breakline + naradio + endnaradio;
      }
  };
  
  function radiovalue(elem, operation, value) {
      if (operation === 'get') {
          return $(elem).val();
      } else if (operation === 'set') {
          if ($(elem).is(':checked') === false) {
              $(elem).filter('[value=' + value + ']').attr('checked', true);
          }
      }
  };
  </code></pre>
  
  <p>my formatter and unformatter code is as follows</p>
  
  <pre><code>dynamicText: function (cellvalue, options, rowObject) {
          if (cellvalue == 'R') {
              return 'Received';
          }
          else if (cellvalue == 'N') {
              return 'NA';
          }
          else {
              return '';
          }
      }
  
  $.extend($.fn.fmatter.dynamicText, {
      unformat: function (cellValue, options, elem) {
          debugger;
          var text = $(elem).text();
          return text === '&amp;nbsp;' ? '' : text;
      }
  });
  </code></pre>
  
  <p>Issue I am having is, when I select a row and check an edit button it doesn't fire set in radiovalue function. It fires get in radiovalue function while creating radio button when a row is selected. Any help so that I can set a value to the radio button?!</p>
  
  <p>Thanks</p>
