Why won't this jQuery loop work?

Why won't this jQuery loop work?

Why won't this work? All I did was put it inside a "while" loop

$(document).ready(function(){
   var i = 1;
   while(i <= 9){
      $(".mp-men" + i).click(function(){
         $("#display").attr("src", "01-bigthumb-" + i ".jpg");
      });   
      ++i;
   }
});
