JQM 1.2.0 and popup problem

JQM 1.2.0 and popup problem

I can't get the popup working.
I'm using Jquery 1.8.2 and JQM 1.2.0.
When I add an popup to my project I don't see the popup when pressing the button.
The popup appears only when I click a button to go to another page. The page disappears, the popup shows for  half a second and the the new page.
Below a simple test for the popup. Clicking the button doesn't show the popup.
What to do?

  1. <!DOCTYPE html>
    <html>
    <head>
        <title>Test</title>
        <link rel="stylesheet" href="jquery.mobile.css" />
        <script type="text/javascript" src="jquery.js"></script>
        <script type="text/javascript" src="jquery.mobile.js"></script>
    </head>
    <body>

    <div data-role="page" data-theme="a" id="home">
        <a href="#popuptest" data-rel="popup">
            <input type='button' value='Test popup'>
        </a>
    </div>

    <div data-role="popup" id="popuptest">
        <p>De stand is:<p>
    </div>
