You don't need to use both the success and complete fn.  You can use
complete like this:

complete: function(xhr, status) {
    if (status == "success") {
        $('ul.notes').append('<li><a href="#">' + xhr.responseText +
'</a></li>');
        var key = XMLHttpRequest.getResponseHeader('Note-Key');
        $('ul.notes > li:last-child a').attr('href', '#' + key);
    }
}
