                    $  ('.link-prev', this.$  node).hide();
                } else {
                    $  ('.link-prev', this.$  node).show();
                };
                var url = this.generateURL(true);
                $  .get(url, this.write.bind(this));
            },
            next: function(e) {
                e.preventDefault();
                this.currentPage++;
                $  ('.link-prev', this.$  node).show();
                if (this.currentPage >= this.totalItems - 1) {
                    this.currentPage = this.totalItems - 1;
                    $  ('.link-next', this.$  node).hide();
                } else {
                    $  ('.link-next', this.$  node).show();
                };
                var url = this.generateURL(true);
                $  .get(url, this.write.bind(this));
            },
