Bootstrap Alert Auto Close

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>
