Dynamically change bootstrap progress bar value wh

Question

I'm trying to make a dynamic checklist with bootstrap progress bar. Here's my markup code

<div class="progress progress-striped active">
    <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100">
    </div>
</div>
<div class="row tasks">
    <div class="col-md-6">
        <p><span><?php echo $title; ?></span><?php echo $description; ?></p>
    </div>
    <div class="col-md-2">
        <label><?php echo $date; ?></label>
    </div>
    <div class="col-md-2">
        <input type="checkbox" name="progress" class="progress" value="<?php echo $progress; ?>">
    </div>
    <div class="col-md-2">
        <input type="checkbox" name="done" class="done" value="<?php echo $done; ?>">
    </div>
</div><!-- tasks -->

What I want to do is when I check on the first checkbox the progressbar value is changed to the checkbox value, and when I check the second one, progressbar value must increment by the second checkbox value and so on

Here's my javascript code

$(document).ready(function() {
  $('.progress').change(function(event) {
    var progress_value = $(this).val();
    var newval = progress_value;
    if ($(this).is(':checked')) {
      $('.progress-bar').css("width", function(i) {
        while(newval < 100) {
          return newval+"%";
          newval+=progress_value;
        }
      });
    } else {
      $('.progress-bar').css("width", function(i) {
        do {
          newval -= progress_value;
          return newval+"%";
        } while(newval >= progress_value);
      });
    }
  });
});

Try this maybe :

Bootply : http://www.bootply.com/106527

Js :

$('input').on('click', function(){
  var valeur = 0;
  $('input:checked').each(function(){
       if ( $(this).attr('value') > valeur )
       {
           valeur =  $(this).attr('value');
       }
  });
  $('.progress-bar').css('width', valeur+'%').attr('aria-valuenow', valeur);    
});

HTML :

 <div class="progress progress-striped active">
        <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100">
        </div>
    </div>
<div class="row tasks">
        <div class="col-md-6">
          <p><span>Identify your campaign audience.</span>Who are we talking to here? Understand your buyer persona before launching into a campaign, so you can target them correctly.</p>
        </div>
        <div class="col-md-2">
          <label>2014-01-29</label>
        </div>
        <div class="col-md-2">
          <input name="progress" class="progress" type="checkbox" value="10">
        </div>
        <div class="col-md-2">
          <input name="done" class="done" type="checkbox" value="20">
        </div>
      </div><!-- tasks -->

<div class="row tasks">
        <div class="col-md-6">
          <p><span>Set your goals + benchmarks</span>Having SMART goals can help you be
sure that you’ll have tangible results to share with the world (or your
boss) at the end of your campaign.</p>
        </div>
        <div class="col-md-2">
          <label>2014-01-25</label>
        </div>
        <div class="col-md-2">
          <input name="progress" class="progress" type="checkbox" value="30">

        <div class="col-md-2">
