Javascript - and infinite loops

I have this snippet of tracking (below) I was looking at why it's possibly making 4 calls each time you click "addToCart.gif". i added "console.log()" to each if case - and noticed it's looping.

Is this because it's calling the same function before the function has ended? is there a better way of doing this that you can advise?

Thank you so much!

<script type="text/javascript">// <![CDATA[
var href = location.href
if(href != "" && href.indexOf("/product/") > 0){

   mboxDefine("clicked-addToCart","clicked-addToCart")
   var count=0;

   function addToCartClickTracking(){
      if(typeof jQuery == 'function' && jQuery(".add-to-cart[src*='addToCart.gif']").length > 0 && count < 10){
         console.log("adding click tracking")
         jQuery(".add-to-cart[src*='addToCart.gif']").click(function(){
            mboxUpdate("clicked-addToCart")
         });
        count=10;
      } else {
         console.log("trying again")
         count++;
         setTimeout(addToCartClickTracking,400);
      }
   }
   addToCartClickTracking();
}
