Unable to make service call in Data tables server side processing

问题

 Javascript

 $('#grid').DataTable({
         "processing": true,
         "destroy": true,
         "scrollY": true,
         "scrollX": true,
         "serverSide": true,
         "paging": true,
         "pageLength": 20,
         "lengthChange": false,
         "language": { search: '', searchPlaceholder: "Search..." },

         "ajax":
         {
             "url":'api/Default/EmployeeDetails',
             "contentType": "application/json",
             "type": 'POST',
             "dataType": "json",
             "data": function (d) {
                 debugger;
                 return JSON.stringify(d);
             },
             "dataSrc": function (json) {
                 debugger;
                 //json.draw = json.draw;
                 //json.recordsTotal = json.recordsTotal;
                 //json.recordsFiltered = json.recordsFiltered;
                 //json.data = json.data;

                 var return_data = json;
                 //return return_data.data;
                 var dttt = $.parseJSON(return_data.data);
                 return dttt;
             }
         },
         "columns": [
             {
                 "data": "UserName",
                 "title": "Employee Name"
             },
             {
                 "data": "Password",
                 "title": "Passwords"
             }, ] 

HTML

 Server side
  [HttpPost("EmployeeDetails")]
         public string EmployeeDetails([FromBody] PagingParams data)
         {
             SQLServerConnect connection = new SQLServerConnect();
             string result = JsonConvert.SerializeObject(connection.EmployeeDetails("Employee", data));
             return result;
         }

I am unable to hit the service call. Ajax call is not initializing. So, unable to make service call to get the data for data tables. There is no error in console also. Help me out from this. Thanks in advance
