Angularjs ng-click: how to get `this` data?

Let say I have this item in the list with angular ng-click event.

<a data-id='102' ng-click='delete()'>Delete</a>

How can I get the data/ info if this then?

        $scope.delete = function() {

             var id = $(this).attr('data-id');
             console.log(id); // I want to get 102 as the result
             if (confirm('Are you sure to delete?')) {
                $('#contactsGrid tr[data-id="' + id + '"]').hide('slow');

            }
         };
