数据未定义

Question

我有这个代码来获取数据，在html中显示并更新它，但是这里的数据是未定义的：

data: {
    id: clickedBox.data('id'),
    nome: clickedBox.data('nome'),
    email: clickedBox.data('email')
}

以下完整代码：

$.ajax({
    type: 'GET',
    //async: false,
    url: 'https://app.myurl.com/reservas',
    success:function(reservas){

        reservas.forEach (function (reserva) {
            var reservasHTML = [];


            reservasHTML.push('<tr class="reservas">');
            reservasHTML.push('<td> <input type="checkbox" class="salvar" data-id="' + reserva._id + '" data-nome="' + reserva.nome + '" data-email="' + reserva.email + '"/> </td>');
            reservasHTML.push('<td>' + reserva._id + '</td>');
            reservasHTML.push('<td>' + reserva.nome + '</td>');
            reservasHTML.push('<td>' + reserva.email + '</td>');
            reservasHTML.push('</tr>');

            $('tbody').append(reservas.join(""));

        })
    },
    error:function(e){
        console.log(e);
    }
});


$(function(){
    $('body').on('click', '.salvar', function(){
       alert('Salvo!');
       var clickedBox = $(this);

       $.ajax({

            type: 'PUT',
            url: 'http://localhost/datas',
            //async: false,
            data: {
                id: clickedBox.data('id'),
                nome: clickedBox.data('nome'),
                email: clickedBox.data('email')
            },
            sucess:function (success) {
                console.log('success')
            },
            error:function(err) {
                console.log(err);
            }
        });
    });
});

如果有人可以帮助我或指导我。我被困在这里几个小时：X

谢谢：）
