Custom URL with event handling

Hi. I have a site where it only makes sense to share my homepage. I barely tweaked your example that shows you how to modify the share event and it works great:

a2a_config.callbacks.push({
    share: function(share_data) {
            // The shared URL
        var old_url = share_data.url;
        // Initialize new shared URL
        var new_url = 'http://www.mysite.com';

        // Modify the share by returning an object
        // with a "url" property containing the new URL
        if (new_url != old_url) {
            return {
                url: new_url
            };
        }
    }
});

However I think it pulls the share count before this function is invoked, because the number shown is the number it would have been had I not done this. Is there any way to work around this? THANKS for this great free plugin!
