angularjs text area character counter

Hi I have a characeter counter for a text area. My problem is that it doesn't count spaces or linebreaks. How do I make it so that it does so?

   <div class="controls">

   <textarea rows="4" cols="50"  maxlength="1500" data-ng-minLength="1" data-ng  
    model="createprofilefields.description" required highlight-on-
    error></textarea>

    <br />

<!--counter-->
  <span class="form-help">{{1500-createprofilefields.description.length}}         
   Characters</span>

    </div>
