When check and Uncheck the Child node checkbox, Parent node checkbox is not working in IE 7 and 8

function CheckUncheckParents(srcChild, check) {
  var parentDiv = GetParentByTagName("div", srcChild);
  var parentNodeTable = parentDiv.previousSibling;
            
  if (parentNodeTable) {
    if (parentNodeTable.attachEvent && parentNodeTable.fireEvent) {
      if (!parentNodeTable.addEventListener && parentNodeTable.attachEvent && parentNodeTable.fireEvent) {
        parentNodeTable.attachEvent("onclick", function click() {
          var checkUncheckSwitch = check;
          var inpElemsInParentTable = parentNodeTable.getElementsByTagName("input");

          if (inpElemsInParentTable.length > 0) {
            var parentNodeChkBox = inpElemsInParentTable[0];
            
            if (checkUncheckSwitch) {
              parentNodeChkBox.checked = checkUncheckSwitch;
            }
                                    
            //do the same recursively
            CheckUncheckParents(parentNodeChkBox, checkUncheckSwitch);
          }
        });
      }
    }
  }
}
