kendo grid 點擊更新沒有反映

由於沒有在dataSource上寫schema

schema: {
          model: {
                id: "DeptId",
                fields: {
                    CompanyId: { editable: false, nullable: true },
                    DeptId: { editable: false, nullable: true },
                    DeptName: { editable: true, nullable: true, type: "string", validation: { required: false } },
                        }
                 }
          }
