Kendo UI JS网格验证未触发

Question

我有一个网格，我想添加一些客户端验证，但我无法弄清楚如何做到这一点。剑道网站上的例子还不够。我错过了一些东西。

这是我的网格代码：

  $(document).ready(function () {
var datasource = new kendo.data.DataSource({
    transport: {
        read: {
            url: '/DiscountPromotion/Get',
            dataType: "json",
        },
        update: {
            url: '/DiscountPromotion/Update',
            dataType: "json",
            type: "POST",
            contentType: "application/json"
        },
        destroy: {
            url: '/DiscountPromotion/Delete',
            dataType: "json",
            type: "POST",
            contentType: "application/json"
        },
        create: {
            url: '/DiscountPromotion/Add',
            dataType: "json",
            type: "POST",
            contentType: "application/json"
        },
        parameterMap: function(options, operation) {
            if (operation !== "read") {
                return JSON.stringify({ discountPromotionViewModel: options });
            }
        },

    },
    pageSize: 10,
    schema: {
        model: {
            id: "Id",
            fields: {
                Id: { type: "number" },
                Code: {
                    validation: {
                        required: true,
                        codevalidation: function (input) {
                            console.log("HÄÄR");
                            if (input.is("[name='Code']") && input.val() != "") {
                                console.log("INTE HÄR");

                                input.attr("data-codevalidation-msg", "Product Name should start with capital letter");
                                return /^[A-Z]/.test(input.val());
                            }
                            return true;
                        }
                    }

                },

                    validation: {
                        required: true,
                        mincostvalidation: function(input) {
                            if (input.val() == 0) {
                                console.log(input);

                                return false;
                            }
                            return true;
                        }

                    }

     var n = 8;

    var text = '';
    var possible = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';

    for (var i = 0; i < n; i++) {

 });

console.log没有一个在控制台中注册任何内容，因此我的验证没有实际被解雇。
