加减号不会与我的手风琴菜单同步

Question

第一个加减号有效...在页面加载时，ul被取消隐藏，图标为减号。其他的也是正确的，并且是加号，但是这些是隐藏的（因此看起来像开放和封闭的手风琴菜单）。

为什么我要点击其他人两次？这会破坏正减去同步。

JS小提琴链接可能有所帮助，但我不知道：http://jsfiddle.net/Ft6tg/

  HTML with a ul with sub uls exists in this system... this is implied.

JS

//navigation.js file 
//opens the accordion on page load
//I made it so that the menu where that link is, is open on page load

//a function

// title for open accordion ul now gets a minus sign put beside it (this is an h2 within an li)
    $(subSectionLi).find('#toggle-icon').html(("<i class='fa fa-minus-circle'></i>"));  

//end of function

//dropdown.js file
//does the toggles on that page, and selects the font awesome circle-plus minus

$("#aside").on('click','div span h2',function(event){
    var el = $(this).parent().parent().parent().find('#dropdown');
    if ( !el.is(':animated') ) {

    $(el).slideToggle('slow');
     event.preventDefault();
     var accordion =  $(this).children('span#toggle-icon');

     var menu = $("#dropdown.dropMenu");
     accordion.toggleClass("closed");


        if ($(accordion).hasClass("closed")){ 
            // change plus/minus icon
            accordion.html("<i class='fa fa-plus-circle'></i>");
            } else {
            accordion.html("<i class='fa fa-minus-circle'></i>");
        }
   }
});
