I'm facing a problem with this example:

<!-- Trigger the modal with a button -->

<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>



<!-- Modal -->

<div id="myModal" class="modal fade" role="dialog">

  <div class="modal-dialog">



    <!-- Modal content-->

    <div class="modal-content">

      <div class="modal-header">

        <button type="button" class="close" data-dismiss="modal">&times;</button>

        <h4 class="modal-title">Modal Header</h4>

      </div>

      <div class="modal-body">

        <p>Some text in the modal.</p>

      </div>

      <div class="modal-footer">

        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>

      </div>

    </div>



  </div>

</div>

As per my understanding the data-dismiss="modal" attribute should close the modal if you click on it, but I don't understand how it works behind the scene. I checked the official documentation at: http://getbootstrap.com/javascript/#modals-examples but there's no explanation.
