How to add Backorders to Bulk Edit Products in Admin using \Administration\Views\Product\BulkEdit.cshtml

What kind of code like this do I need to add there?

{
                                        field: "Sku",
                                        title: "@T("Admin.Catalog.BulkEdit.Fields.Sku")",
                                        width: 150
                                    }, {
                                        field: "Price",
                                        title: "@T("Admin.Catalog.BulkEdit.Fields.Price")",
                                        width: 150,
                                        editor: function (container, options) {
                                            $('<input name="' + options.field + '"/>')
                                                .appendTo(container)
                                                .kendoNumericTextBox({
                                                    format: "{0:n4}",
                                                    decimals: 4
                                                });
                                        }
                                    }, {
                                        field: "OldPrice",
                                        title: "@T("Admin.Catalog.BulkEdit.Fields.OldPrice")",
                                        width: 150,
                                        editor: function (container, options) {
                                            $('<input name="' + options.field + '"/>')
                                                .appendTo(container)
                                                .kendoNumericTextBox({
                                                    format: "{0:n4}",
                                                    decimals: 4
                                                });
                                        }
                                    }, {
                                        field: "ManageInventoryMethod",
                                        title: "@T("Admin.Catalog.BulkEdit.Fields.ManageInventoryMethod")",
                                        width: 150
                                    }, {
                                        field: "StockQuantity",
                                        title: "@T("Admin.Catalog.BulkEdit.Fields.StockQuantity")",
                    attributes: { style: "font-size:20px;font-weight:bold;color:crimson" },
                                        //integer format
                                        format: "{0:0}",
                                        width: 150
                                    }

Thanks in advance...!

You would need to first need to change the Data Select function called here

                                            read: {
                                                url: "@Html.Raw(Url.Action("BulkEditSelect", "Product"))",
                                                type: "POST",
                                                dataType: "json",
                                                data: additionalData
                                            },

and edit
        public virtual ActionResult BulkEditSelect(DataSourceRequest command, BulkEditListModel model)
in
nopCommerce_3.90_Source\Presentation\Nop.Web\Administration\Controllers\ProductController.cs

To add the BackorderMode, etc fields.
Then you add extra code from above
