var dialog = $("#classifications").dialog({
        autoOpen: false,

                    success: function(msg) {
                        $(".list-clsfi").html(msg);
                    }
                });
                $("#classifications").dialog('close');
            }
        }
    });
    $("#addClassification").on('click', function(e) {
        e.preventDefault();
        $.get('{{ list_classifications_path(hash_key) }}', function(msg) {
            dialog.dialog('open').html(msg);
        });
