未捕获的TypeError：无法读取属性＆＃39;设置＆＃39;未定义的ajax异步

Question

我有代码

  $.ajax('@Url.Action("Surface", "Data")', { async: true, data: { side: i, StartCountForSurface: StartCountForSurface, EndCountForSurface: EndCountForSurface, IsEdit: "true" } })
        .success(function(e) {

            $("#InsertPartial" + i + "").before(e);
            CalculationAS();
            ////отключение валидации

        }).error(function(e) {
            alert(e);
        });

当我设置async：false时，出现错误Uncaught TypeError：无法读取属性＆＃39;设置＆＃39;查询验证插件中未定义的

更新

javascript代码

   $("[identificationforcountside]").each(function(ind, element) {
        $(element)[0].value = ArrayOfSides[ind].length;
        AddSurface(ind+1);    <---ajax is here

    });
