javascript inside an admin menu?

This isn’t meant to be a double post but my other post is broken for some reason.

The alert() on this admin page doesn’t work, can I not put javascript here?

<?php

add_action('admin_menu', 'mt_add_pages');
function mt_add_pages() {
add_menu_page(__('Test Toplevel','menu-test'), __('Test Toplevel','menu-test'), 'manage_options', 'mt-top-level-handle', 'mt_toplevel_page' );
}
function mt_toplevel_page() {
    echo "<h2>" . __( 'Test Toplevel', 'menu-test' ) . "</h2>";

echo "<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js'></script>
<script language='text/javascript'>

alert('test');
        </script>
";

?>

<div id='test'>asdf</div>

<?php

}

?>
