"columns": [
                        { data: 1 },
                        { data: 2 },
                        { data: 3 },
                        {"defaultContent":"<button type='button' class='editarprueba btn btn-warning' ideditar='+{ data: 1 }+' data-toggle='modal' data-target='#edicion'>Editar</button>"}
                    ]

ideditar='+{ data: 1 }+'
I want to add the data to certain attributes, but I don't know what is the best way to do it, which is similar to the example

example edit button

{

                        "render": function ( data, type, row ) {

                            var idus = $('#variable_sesion2').val();
                            var user = $('#variable_sesion').val();

                            console.log(row[0]);


                            return '<div class="btn-group" role="group" aria-label="Third group"><button class="btn btn-warning btnEdit manito-clic" editMp='+row['0']+' idUs='+idus+' User='+user+' data-toggle="modal" data-target="#modalEditarTable"><i class="fa fa-pencil"></i></button> </div> <div class="btn-group" role="group" aria-label="Third group"> <button class="btn btn-danger btnDeletedt manito-clic" deleteid='+row['cod_id']+' lotep='+row[3]+' viajep='+row[5]+'><i class="fa fa-times"></i></button></div>';

                        }
                    }
