click if else not working...? sometimes

click if else not working...? sometimes

Hello,
I am trying to build a tree menu that uses ajax. I have been able to get it working some of the time.
My problem is with the click function below. I originally used a toggle but since it is not bound to a
live event because this is has ajax generated content it would not work.

I am using a if else detecting if the object is hidden or not. It works some of the time but not all of the time?
I click and nothing happens. I looked in firebug at the console and there seem to be no errors?

Does anyone have any suggestions on how I can use the .toggle with .live or how I can redo my if else so
that it works every time?

Thanks!




$('.ahref',this).live("click", function(){
   
     
   var id = $(this).attr('id');
   
   var subid = $(this).attr('href');
   
   if($('.sub'+subid).is(':hidden')) {

   if($('.sub'+id).text() == '') {    
     //$("div.sub"+id).append("sub menus goes here");
        var rand = '?random=' + Math.random();
             
      $.getJSON('mclicks.php'+rand,{subid:subid,id:id},function(data){ 
          $.each(data, function(i,item){                         
          $.each(item, function(intIndex, objValue) {
            // console.log(this);
             $("div.sub"+subid).append("<a class='ahref' href='" + intIndex + "' onclick='return false;'>" + objValue + "</a> <div class='sub" + intIndex + " data'></div><br /> ");
           });         
          });
         
        }); 
      
     $(".sub"+subid).addClass("data").slideDown(100);

   } // end of blank text check...
} else {
     $('.sub'+subid).slideUp(100);
     $("div.sub"+subid).html("");
}

     }, function () { 
        // $(this).html('Hide Clicks'); 
        $('.sub'+subid).slideUp(100);   
  });
