How to add a new code in this code?

hi
my code is :

function sofGetVideoId($el) {
			var $menu = $el.closest('.menu-3dot-container');
			return parseInt($menu.data('video-id')) || 0;
		}

		function sofUpdateSaveButton(videoId, saved) {
			sofSavedStatus[videoId] = saved;
			var $btn = $('.menu-3dot-container[data-video-id="' + videoId + '"] .sof-save-video');
			if (saved) {
				$btn.text('saved').addClass('sof-already-saved');
			} else {
				$btn.text('save to list').removeClass('sof-already-saved');
			}
		}

		function sofShowListSelector(videoId, $btn) {
			$('.sof-list-dropdown').remove();

			$.ajax({
				url: sofAjaxUrl,
				data: { action: 'get_lists' },
				dataType: 'json',
				success: function(lists) {
					if (!lists || lists.error) return;

					var html = '<div class="sof-list-dropdown" data-video-id="' + videoId + '">';
					html += '<div class="sof-list-dropdown-header"><span class="sof-list-dropdown-title">Save to:</span><span class="sof-list-dropdown-close">&times;</span></div>';

					$.each(lists, function(i, list) {
						var listName = $('<span>').text(list.list_name).html();
						html += '<div class="sof-list-option" data-list-id="' + list.id + '" data-video-id="' + videoId + '">';
						html += listName;
						html += '</div>';
					});

					html += '<div class="sof-list-new">';
					html += '<input type="text" class="sof-new-list-input" placeholder="New list name..." maxlength="100" />';
					html += '<span class="sof-new-list-add" data-video-id="' + videoId + '">+</span>';
					html += '</div>';
					html += '</div>';

					$('body').append(html);

					var rect = $btn[0].getBoundingClientRect();
					var $dd = $('.sof-list-dropdown');
					var ddH = $dd.outerHeight();
					var top = rect.top - ddH - 4;
					if (top < 5) {
						top = rect.bottom + 4;
					}
					$dd.css({
						top: top + 'px',
						left: rect.left + 'px',
						width: '200px'
					});
				}
			});
		}

$btn.text(‘saved’).addClass(‘sof-already-saved’);
