google maps click on blackberry mobile web

I'm having trouble getting the click event on a google map trigger in a blackberry web environment. The click bubbles up to the div wrapper and gets triggered, but never tri开发者_JAVA技巧ggers the internal maps event.

I've setup a test page at http://www.codenothing.com/dev/2011/blackberry-map-click/index.html with alerts attached to element click handle and map click handle. Here's the javascript on the page:

function MapsLoaded(){
    var elem = document.getElementById( 'map' ),
        map = new google.maps.Map( elem, {
            mapTypeControl: false,
            overviewMapControl: false,
            scrollwheel: false,
            streetViewControl: false,
            panControl: true,
            navigationControl: true,
            navigationControlOptions: {
                style: google.maps.NavigationControlStyle.SMALL
            },
            zoom: 16,
            center: new google.maps.LatLng( 37.78778, -122.407637 ),
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });

    elem.addEventListener( 'click', function(){
        alert( 'Element Click' );
    }, false);

    google.maps.event.addListener( map, 'click', function(){
        alert( 'Map Click' );
    });
}

window.onload = function(){
    var script = document.createElement('script');
    script.type = "text/javascript";
    script.src = "http://maps.google.com/maps/api/js?sensor=true&callback=MapsLoaded";
    document.body.appendChild( script );
};
