Mootools Form Post Problem, Abort increasingly+1 with each request

Question

Hi all, i'm using Mootools 1.2. Ihave 15 Forms with same name only change in their id's like form1, form2, form3, ... ,form15 same with their elements. i need to submit all forms by ajax. For that purpos i make a function and call them on each functions onClick event. function is

function addStepConfiguration(id,mystrip,comment,error,submitid,i) {
 $(id).addEvent('submit', function(e) {
  e.stop();
  $(submitid).setStyle('display','none');
  loading_Img(i);
  this.set('send', {
   onComplete: function(responseText) {
    $('loading_img'+i).innerHTML = '';
    SplittedResText = responseText.split("|");
    if(SplittedResText[1]=='undefined') {
     $(error).innerHTML=SplittedResText[0];
    } else {
     $(comment).innerHTML=SplittedResText[0];
     $(mystrip).set('class',SplittedResText[1]);
     removeMsg.delay(20,'',error);
     removeMsg.delay(1500,'',comment);
    }
    $(submitid).setStyle('display','block');
   }
  });
  this.send();
 });
}

When i submit a form say first one then it submitted and give response normally, but in second time without page refresh, it abort the request one time. in third attempt it abort 2 times..then go on +1 each time. It gives no error, just abort and again request automatically. i can't understand what is the problem. please any one can help me.
