jQuery Mobile 1.4.x: How can I put a popup after 5 seconds the app starts

I can't do a click event it's suppose that the popup starts after 5 seconds after the app runs.

Any ideas?

UPDATE:

Here is the iFrame Popup example. I just changed the src from where the ads are going to come from.

The isue is that I need to set a timeout after 5 seconds to use the popup, but I'm a little confused on how will the timeout function will render the popup because I can't use a click event.

<a href="#popupMap" data-rel="popup" data-position-to="window" class="ui-btn ui-corner-all ui-shadow ui-btn-inline">Open Map</a>
<div data-role="popup" id="popupMap" data-overlay-theme="a" data-theme="a" data-corners="false" data-tolerance="15,15">
    <a href="#" data-rel="back" class="ui-btn ui-btn-b ui-corner-all ui-shadow ui-btn-a ui-icon-delete ui-btn-icon-notext ui-btn-right">Close</a>
    <iframe src="http://googleadmobORadsense.com" width="480" height="320" seamless=""></iframe>
</div>

$(document).on("mobileinit", function () {
  setTimeout(function () {
    //show your popup here
  }, 5000);
});
