[jQuery] How to use the simple modal if there are two modal windows need be pop-up on ready method?

[camel]

Hi all
     How to use the simple modal if there are two modal windows need
be pop-up on ready method?
I use the confirm style of simple modal and only the fist window can
be pop-up, the second doesn't work.
      thanks for your help.
      thanks

BTW: the code of javascript is following

<script type="text/javascript">
   $(document).ready(function(){
        $('#confirm').modal({
                        close:false,
                        position: ["20%",],
                        overlayId:'confirmModalOverlay',
                        containerId:'confirmModalContainer',
                        onShow: function (dialog) {
                                dialog.data.find('.yes').click(function () {
                                        alert("click Yes in the confirm 
window.");
                                        $.modal.close();
                                });
                        }
            });
   });
   $(document).ready(function(){
        $('#duplicated').modal({
                        close:false,
                        position: ["20%",],
                        overlayId:'confirmModalOverlay',
                        containerId:'confirmModalContainer',
                        onShow: function (dialog) {
                                dialog.data.find('.yes').click(function () {
                                        alert("click Yes");
                                        $.modal.close();
                                });
                        }
            });
   });
</script>
