I want to send data to the controller inside the method and I have this error ts.1005

if (edit === true) {
  updateTodo(update) {
    todoListItemSpan.contentEditable = true;
    todoListItemSpan.addEventListener("keyup", () => {
      todoTextUpdate = todoListItemSpan.textContent;
      update(id, todoTextUpdate);
    });
  }

}
