        this.cardslist = cardslist;
        notifyDataSetChanged();

    }

I just correct my data

 alert.setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog, int which) {

                                    final String newNameCardString = nameCardEditText.getText().toString();
                                    int indexOf = cardslist.get(position).setNameCard(newNameCardString);
                                    cardslist.set(indexOf, card);
                                    notifyItemChanged(indexOf);

                                }
                            });

It works :)
