Bootstrap alert shows up only once in JSFiddle

When I click the save button on the first time, the alert shows up fine. But every time after that, the alert doesn’t show up unless I do a hard refresh.

Here is the JSFiddle: JSFiddle

$("#success-alert").hide();
$("#saveChange").click(function showAlert() {
  $("#success-alert").alert();
  $("#success-alert").fadeTo(2000, 500).slideUp(500, function() {
    $("#success-alert").alert('close');
  });
});

<div class="product-options">
  <button id="saveChange" href="javascript:;" class="btn btn-mini">Save</button>
</div>
<div class="alert alert-success" id="success-alert">
  <button type="button" class="close" data-dismiss="alert">x</button>
  <strong>Success! </strong>

Answer

the line

$("#success-alert").alert('close');

destroys your alert so you cannot open it again.
remove that line and your alert will show each time
