SetInterval problem

Hello guys i have this function to make a percent text go from 0% to 65%(example), but this not working on varius elements just in one 

$.fn.textPorcent = function() {
  var $percent = $(this);
  curr = parseInt($(this).text());
  to = $(this).data("porcentaje");
  counter = setInterval(function() {  
          if(curr <= to)
          {
              $percent.text((curr++)+'%');
           }
      }, 10);
};

$("#span1").textPorcent();
$("#span2").textPorcent();
$("#span3").textPorcent();
$("#span4").textPorcent();

<span id="span1" data-porcentaje="95">0%</span>
<span id="span2" data-porcentaje="95">0%</span>
<span id="span3" data-porcentaje="75">0%</span>

Your element IDs are all the same (span1).
