You can redirect to another page in notification success callback. Like in iOS:

function onNotificationAPN (event) {
    if ( event.alert )
    {
       document.location.href = 'path to your file/notification.html';
    }
}

and in Android:

var onNotificationGCM = function(e) {
    // Check which event:
    switch(e.event)
    {
        case 'registered' :
        {
            deviceToken = e.regid;
            break;
        }
        case 'message':
        {
            // this is the actual push notification. its format depends on the data model from the push server
            var message = e.message;
            document.location.href = 'path to your file/notification.html';
            break;
        }
    }
};
