jQuery Grid Plugin - jqGrid

Hi,

I have a column with a checkbox and want to react on a click inside the edit form (where the checkbox is visible and clickable). The reason is, that I want to set some textboxes inside the edit form depending on the checkbox's value (0:1). I found Oleg's code:

    var iCol = getColumnIndexByName ($(this), 'ebl'), rows = this.rows, i,
              c = rows.length;
          
              for (i = 1; i < c; i += 1) {
                  $(('input[type="checkbox"]'),rows[i].cells[iCol]).click(function (e) {
                      var id = $(e.target).closest('tr')[0].id,
                          isChecked = $(e.target).is(':checked');
                      alert('clicked on the checkbox in the row with id=' + id +
                            '\nNow the checkbox is ' +
                            (isChecked? 'checked': 'not checked'));
                  });
              }

That does work inside the grid, but not in the edit form. How would  I need to change the function? And would it have to be called in beforeShowForm of the edit form?

Thanks,
