Jquerey Update Done More Than One Time

Hi,

I am using jQuery to update the user inputed data in the comments field. jQuery event will be triggered when even the focus was blur

$(document).ready(function(){
   $('#mycontrolid').live('blur',function(){

     //code to update the comments

   });
});

some times the save action was triggered multiple times , how to solve this?

Any one faced the same problem?
