使用字符串primaryKey删除行

我有一个Infregistics网格,当网格的primaryKey是dataType字符串时,我无法删除行。

我无法将primaryKey设置为dataType编号,因为它的格式为:“KIT_001”。有没有什么巧妙的方法可以使用删除按钮并删除包含此类数据的行?也许有一种方法可以设置递增的ID并将其用于删除按钮?

var dataSource = [
    {"ProductID": "KIT_001", "Name": "Kit 1", "ProductNumber": "P4857"},
    {"ProductID": "KIT_002", "Name": "Kit 2", "ProductNumber": "P4567"},
    {"ProductID": "KIT_003", "Name": "Kit 3", "ProductNumber": "P4447"}
]
$(function () {
            $("#grid").igGrid({
                autoGenerateColumns: false,
                width: "100%",
                height: "500px",
                columns: [
                    { headerText: "Product ID", key: "ProductID", dataType: "string", width: "10%" },
                    { headerText: "Product Name", key: "Name", dataType: "string", width: "30%" },
                    { headerText: "Product Number", key: "ProductNumber", dataType: "string", width: "25%" },
                    { headerText: "", key: "Delete", dataType: "string", width: "10%", unbound: true, 
                     template: "<input type='button' onclick='deleteRow(${ProductID})' value='Delete' class='delete-button'/>"},
                ],
                primaryKey: "ProductID",
                dataSource: dataSource,
                features: [
                    {
                        name: "Updating",
                        enableAddRow: false,
                        editMode: "row",
                        enableDeleteRow: false,

                    }
                    ]
            });
        });

        function deleteRow(rowId) { console.log('rowId ',rowId)
            var grid = $("#grid").data("igGrid");
            grid.dataSource.deleteRow(rowId);
            grid.commit();
        }
