Bootstrap Alert Auto Close

Question

My need is to call alert when I click on Add to Wishlist button and should disappear the alert in 2 secs. This is how I tried, but the alert is disappearing instantly as soon as it is appearing. Not sure, where the bug is.. Can anyone help me out?

JS Script

$(document).ready (function(){
   $("#success-alert").hide();
   $("#myWish").click(function showAlert() {
      $("#success-alert").alert();
      window.setTimeout(function () { 
         $("#success-alert").alert('close'); 
      }, 2000);             
   });      
});

HTML Code:

<div class="product-options">
   <a id="myWish" href="" class="btn btn-mini">Add to Wishlist </a>
   <a href="#" class="btn btn-mini"> Purchase </a>
</div>

Alert Box:

<div class="alert alert-success" id="success-alert">
   <button type="button" class="close" data-dismiss="alert">x</button>
   <strong>Success!</strong>
   Product have added to your wishlist.
</div>

For a smooth slideup:

$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
    $("#success-alert").slideUp(500);
});

$(document).ready(function() {
  $("#success-alert").hide();
  $("#myWish").click(function showAlert() {
    $("#success-alert").fadeTo(2000, 500).slideUp(500, function() {
      $("#success-alert").slideUp(500);
    });
  });
});
