Set every td ID with corresponding columns data name (server side processing)

dabee

Hello
I have this kind of init (simplified):

 oTable = $('#form_list').DataTable( {
        'serverSide': true,
        'processing': true,
        'ajax':{
            'url': 'api/ssp_forms',
            'type': 'POST'
        },
        'columns': [
            { data: 'booking_id' },
            { data: 'booking_date' },
        ],
        'columnDefs': [
            {'targets': ['_all'], 'createdCell': function (td, cellData, rowData, row, col) {
                    //perhaps some code here to set IDs
                }
            }
        ]
    });

I get this response from my api:

{  
   "draw":1,
   "recordsTotal":70,
   "recordsFiltered":2,
   "data":[  
      {  
         "booking_id":"25",
         "booking_date":"01.10.2016",
      },
      {  
         "booking_id":"13",
         "booking_date":"30.09.2016",
      }
   ]
}

How do I set first td's ID as "booking_id", and second td's ID as "booking_date" automatically?

Thanks in advance
