asp.net-mvc - kendo ui Grid“弹出模式”，编辑和删除按钮，不触发控制器动作

Question

这是我的 kendo ui 网格视图，它的读取功能触发得很好，但是当我想更新时问题才开始，我的控制器中的更新功能甚至没有触发，

<script>

    $(document).ready(function () {
        var dataSource = {
            transport: {
                type: "json",
                read: {
                    url: "@Html.Raw(Url.Action("CommentList", "Comment"))",
                    type: "POST",
                    dataType: "json"
                },
                update: {
                    url: "@Html.Raw(Url.Action("CommentUpdate", "Comment"))",
                    type: "POST",
                    dataType: "json"
                },
                destroy: {
                    url: "@Html.Raw(Url.Action("CommentDelete", "Comment"))",
                    type: "POST",
                    dataType: "json"
                }
            },
            schema: {
                data: "Data",
                total: "Total",
                errors: "Errors",
                model: {
                    id: "Id",
                    fields: {
                        Id: { type: "number" },
                        ProductName: { editable: false, type: "string"},
                        ProductPicture: { editable: false, type: "string"},
                        Text: { editable: false, type: "string"},
                        AdminConfirm: { editable: true, type: "boolean", validation: { required: true } }
                    }
                }
            },
            requestEnd: function (e) {
                if (e.type === "create" || e.type === "update") {
                    this.read();
                }
            },
            error: function (e) {
                alert("something wrong!");
                // Cancel the changes
                this.cancelChanges();
            },
            pageSize: 15,
            serverPaging: true,
            serverFiltering: true,
            serverSorting: true
        };
        $("#grid").kendoGrid({
            dataSource: dataSource,
            pageable: {
                refresh: true,
                pageSizes: [10, 15, 20, 30, 50]
            },
            height: 550,
            columns: [
                {
                    field: "ProductName",
                    title: "product name",
                    width: "90px"
                },
               {
                   field: "ProductPicture",
                   title: "picture",
                   width: "100px",
               },
                {
                    field: "Text",
                    title: "comment",
                    width: "180px"
                },


                 {
                     field: "AdminConfirm",
                     title: "adminconfirm",
                     width: "70px",

                 },
                {
                    command: [
                        {
                            name: "edit" , text: { // sets the text of the "Edit", "Update" and "Cancel" buttons
                                edit: "edit",
                                update: "update",
                                cancel: "cancel"
                            }
                        }
                    ],
                    title: "&nbsp;", width: "250px"
                }
            ],

            editable  : {
                mode : "popup",
                window : {
                    title: "confirmation form"
                }}
        });
    });

  </script>
 </div>

这是我的第一行更新函数

    [HttpPost]
       public ActionResult CommentUpdate(DataSourceRequest request, CommentViewModel comment)

有人知道为什么吗？提前感谢
