jquery - Update jquery cookie pb after addClass , some div shouldn't take class cookie created

Question

Thanks to Arun P Johny i achieve this code bellow but , there still a pb , Basicly, you click on a div then add class green background, so i'd like to keep the class after reload the page and i use jquery cookie plugin to achieve it, pb is div without checkboxes checked should not take the active class after page reloading, but unfortunatly its the case..

var $qsts = $(".quest").show();
var $anrs = $(".ans").hide();

$('.quest').click(function(){
    var $ans = $(this).next().toggle(10);
    $anrs.not($ans).hide();
});

$('.ans').change(function(){
    var $ans = $(this).closest('.ans');
    var $act = $ans.prev().toggleClass('question-active', $ans.find('input:checkbox:checked').length > 0)

    if($act.hasClass('question-active')){
        $.cookie('question-active', $act.get(0).className.match(/\b(question\d*)\b/)[1])
    } else {
        $.removeCookie('question-active');
    }
});

var active = $.cookie('question-active');
if(active){
    $qsts.filter('.' + active).addClass('question-active')
}

Here is the complete code : http://jsfiddle.net/arunpjohny/hZeyd/7/
