Как для чтения с экрана прочитать заголовок столбца в pqgrid

Question

здесь я пытаюсь, чтобы программа чтения с экрана NVDA прочитала имя столбца, но он не работает

searchOrgGrid = $('#gridSearchOrgs');
    var columnModel = [{
        title: "",
        dataIndx: "UID",
        hidden: true,
        width: 100,
        align: "left"
      },
      {
        title: nmc.platform.strings.Name,
        dataIndx: "Name",
        width: 200,
        align: "left",
        header: true,
        dataType: function(val1, val2) {
          return NMCApp.stringSort(val1, val2);
        }
      },
