Kendo UI ListView排序无法正常工作

Question

我有一个无法排序的列表视图。当我拖放项目，并且Ajax调用存储过程来更新显示顺序时，这些项目将恢复为原始顺序。

数据库正在更新，所以我知道它不是数据库问题。没有错误消息，存储过程返回＆＃34;成功＆＃34;。也许我有列表视图和可排序设置错误？

var DataSource;
$("#VideoView").kendoListView({
    dataSource: {
        type: "json",
        transport: {
            read: {
                type: "Get",
                contentType: "application/json; charset=utf-8",
                url: "../api/Admin_Videos",
                dataType: "json"
            },
            timeout: 120000
        },
        sort: [{ field: "DisplayOrder", dir: "asc" }],
        serverSorting: true
    },
    dataBound: function () {
        $(this.items()).on("dblclick", function () {
            data = DataSource[$("div.product").index(this)];
            EditVideo(data);
        });
    },
    dataBinding: function() {
        DataSource = this.dataSource.data();
    },
    template: kendo.template($("#VideoViewTemplate").html())
});

$("#VideoView").kendoSortable({
    filter: ">div.product",
    cursor: "move",
    placeholder: function (element) {
        return element.clone().css("opacity", 0.1);
    },
    hint: function (element) {
        return element.clone().removeClass("k-state-selected");
    },
    change: function (e) {
        var items = $("#VideoView").data("kendoListView").items();
        var itemList = items.children("img");
        var newList = '';

        for (var i = 0; i < items.length; i++) {
            newList = newList + itemList.eq(i).attr("id") + ','
        }
        newList = newList.substring(0, newList.length - 1);

        $.ajax({
            type: "Post",
            contentType: "application/json; charset=utf-8",
            url: "../api/Admin_VideoReorder",
            datatype: "json",
            data: JSON.stringify({ ID: newList }),
            success: function (d) {
                // rebind data
                $("#VideoView").data("kendoListView").dataSource.read();
            }
        });
    }
});
