How to select default value on loading dynamic kendo dropdownlist

-
//calling the below function to get the weekendingdates from database using ajax call

ex:  function GetWeekEndingDates() {
            $.ajax({
                type: 'GET',
                url: "WS_Equipment.asmx/GetWeekendingDate",
                dataType: "json",
                success: function (jsonData) {
                    var i = JSON.parse(JSON.stringify(jsonData));
                    if (jsonData != null) {
                        WeekDates = i.WeekEndingDates;
                        LastWeekDate = i.LastWeekEndingDate;
                        BindDropDown();
                    }
                },
                error: function (error) {
                    alert(error.responseText)
                }
            });
        }

 //calling the below function to bind the data to kendo dropdown as datasource

ex: function BindDropDown() {
            WeekDates = new kendo.data.DataSource({
                data: WeekDates,
                batch: true,
                schema: {
                    model: {
                        fields: {
                            WeekendingValue: { type: "string" }
                        }
                    },

                }
            });
       }

 //kendo dropdown with datasource

ex: $("#products").kendoDropDownList({
                filter: "contains",
                optionLabel: "Select WeekEndingDate",
                dataTextField: "WeekendingValue",
                dataValueField: "WeekendingValue",
                virtual: {
                    itemHeight: 26,
                    valueMapper: function (options) {

                    }
                },
                dataSource: WeekDates
            }).data("kendoDropDownList").select(1);       


In the above data("kendoDropDownList").select(1) is used to select the value at index 1 by default In this case as Iam bringing the weekendingdates in desc order,so the last weekendingdate will be first in order and selected by default.
