无法在ajax中击中.done功能

Question

这是我的ajax代码。我的控制器方法正在命中，但它不会.done函数。

 $.ajax('/Account/ChangePassword', {
                "data": $form.serialize() + "&userId=" + $scope.data.LoginResponce.UserId,
                "type": "POST"
            })
            .done(function (data, textStatus, jqXHR) {
                if (data.Result) {
                    $("#ChangePasswordModel").modal('hide');
                    bootbox.alert(data.Message + " Please login with new credentials");
                    $('#change-password-form')[0].reset();
                    $('#change-password-form').data('formValidation').resetForm();
                    $(".password-progress").addClass("hide");
                }
                else {
                    $scope.data.ChangePasswordResponceMessage = 'Unable to change the password now. ' + data.Message;
                    $scope.$apply();
                }
            })
            .fail(function (jqXHR, textStatus, errorThrown) {
                $scope.data.ChangePasswordResponceMessage = 'Some unexpected error occurred. ' + errorThrown;
                $scope.$apply();
            })
            .always(function (jqXHR, textStatus, errorThrown) {
                waitingDialog.hide();
            });
