Your code is working perfectly, what you have to ensure is that the HTML does not contain any spaces or other types of characters other than numbers inside. Example: If your code looks like this:

  <div class="user-coins-value middle-block">
     5
  </div>

Switch to:

 <div class="user-coins-value middle-block">5</div>
