Circular-slider adding symbols

[Mirco]

I almost solved it with this code:

Code:

$('.example .circularslider-max').on("vclick", function() {
   setTimeout(function() {
     var val = $('.example .circularslider-value').text();
     if (val == "1" || val == "2" || val == "3")
     {
       val = "+" + val;
       $('.example .circularslider-value').text(val);
     }
   }, 120);
 });

But it doesn't work really well because sometimes the other script overwritten the value..
