我的DropDown编辑器对jqxGrid列有什么问题？

Question

我有这个jqxGrid设置：

var paymentSource = {
    datatype: "json",
    datafields: [
        { name: 'Id', type: 'number' },
        { name: 'Name', type: 'string' }
    ],
    url: "@Url.Action("GetPaymentSchemes")"
};
var paymentAdapter = new $.jqx.dataAdapter(paymentSource, { autoBind: true });

var gridSource =
{
    datatype: "json",
    datafields: [
        { name: 'Name', type: 'string' },
        { name: 'PaymentSchemeId', type: 'number' },
        { name: 'IsActive', type: 'boolean' },
        { name: 'Remarks', type: 'string' }
    ],
    url: "@Url.Action("GetParkades")"
};

var gridDataAdapter = new $.jqx.dataAdapter(gridSource);
$("#index-grid").jqxGrid(
    {
        theme: theme,
        width: 900,
        source: gridDataAdapter,
        editable: true,
        columns: [
            { text: "Name", datafield: "Name", width: 300 },
            {
                text: 'Payment Scheme',
                datafield: 'PaymentSchemeId',
                displayfield: 'Name',
                columntype: 'dropdownlist',
                createeditor: function(row, value, editor) {
                    editor.jqxDropDownList({ source: paymentAdapter, displayMember: 'Name', valueMember: 'Id' });
                }
            },
            { text: "Active", datafield: "IsActive", width: 50, columntype: 'checkbox' },
            { text: "Operator Remarks", datafield: "Remarks" }
        ]
    });

“付款方案”列显示与页面加载时“名称”列相同的文本值。当我双击“付款方案”时，我会得到正确填充的下拉列表，但是当我选择一个值并让单元格结束编辑时，“名称”列现在显示与“付款方案”列相同的文本。不同来源和适配器中的两个Name字段是否冲突？这是什么？
