jQuery ajax this.id undefined

I have a list of items I delete using AJAX.

This list is a simple list with divs and each div as an id so when the item is removed from the database I return true and then it removes the line.

Here my code:

HTML

<div id="row1">
<div>item1</div>
<div><a href="...">view</a></div>
<div><a id="1">delete</a></div>
</div>

JS

$('.delete').click(function () {
    if (!confirm('Are you sure you want to delete?')) {
        return false;
    }
    $.ajax({
        type: "POST",
        url: '/delete_record',
        data: 'id=' + this.id,
        cache: false,
        success: function (result) {
            if (result == 'good') {
                $('#row' + this.id).remove();
            }
        }
    });
});

For some reason the this.id does not work because this.id is undefined ... why? I have id="1" on my a href.
