I want to do this with ajax, like in dataTables ... it doesn't work for me

[ivanric]

$('#example').treeTable({
	"processing": true,
    "serverSide": true,
    "ajax": {
    	"type": "POST",
        "url": "../actividad_csk/obtenerTreeList",
    	"data": function ( d ) {

        }
  	},
retrieve: true,
    "columns": [
        {
            "data": "id"
            "data": "nombre"
        }
    ],
  	  "createdRow": function ( row, data, index ){
	    	$('td',row).eq(0).html('Modulo #'+data.num);
	    	if(data.estado==1){
	    	btnGroup='';
	    		btnGroup+='<button class="btn btn-xs btn-primary modificar"  data-toggle="tooltip" data-placement="top" title="Modificar" data-id="'+data.idmod+'"><i class="fa fa-edit"></i> | modificar</button>';
	    		btnGroup+='<button class="btn btn-xs btn-danger eliminar"  data-toggle="tooltip" data-placement="top" title="Eliminar" data-id="'+data.idmod+'"><i class="glyphicon glyphicon-remove-sign"></i> | eliminar</button>';
	    		$('td', row).eq(4).html('<div class="btn-group">'+btnGroup+'</div>');
	    	}
        },
});
