ajax, jquery code:

$(document).ready(function () {     $("#btninsertinconsignee").click(function () {         var con = {};         debugger;         con.name = $("#consigneename").val();         con.address1 = $("#regofficeaddress1").val();         con.address2 = $("#regofficeaddress2").val();         con.address3 = $("#regofficeaddress3").val();         con.city = $("#city").val();         con.country = $("#countryaddress").val();         con.pincode = $("#pincode").val();         con.telno1 = $("#telephoneno").val();         con.telno2 = $("#faxno").val();         con.telno3 = $("#mobileno").val();         con.contactperson = $("#contactperson").val();         con.emailid = $("#email").val();         con.remark = $("#remark").val();          $.ajax({                     type: "post",                     url: "consigneewithboot.aspx/insertdata",                     data: '{consignee: ' + json.stringify(con) + '}',                     datatype: "json",                     contenttype: "application/json; charset=utf-8",                     success: function () {                         debugger;                         alert("user has been added successfully.");                         debugger;                          //window.location.reload();                        },                     error: function () {                         debugger;                         alert("error while inserting data");                     }                 });                 return false;              });          });

inserdata function dosen't call executenonquery persist data in database command.
