How to get Twitter Bootstrap Modal's invoker element?

I have got a a element for invoking modal:

<a class="btn" data-toggle="modal" data-target="#myModal" href="http://some-url" >Launch Modal</a>

And, say this is my modal:

<div class="modal hide" id="myModal">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">×</button>
    <h3>Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" class="btn" data-dismiss="modal">Close</a>
    <a href="#" class="btn btn-primary">Save changes</a>
  </div>
</div>

I can bind functions to events fired by modal:

$('#myModal').on('hidden', function () {
  // do something…
})

My question is: How can i access the a element -which invoked the modal- from my event subscriber function?
