Sometimes I need to change the menu without reloading the page. 

More specifically: 

response.menu = [
    .........................
    .........................
    ('Cart (' + str(howManyItemsInCart()) + ")", False, 
URL('catalog','cart'), []),
]

I do control the event when the cart content changes (without reloading the 
page), so javascript can be inserted there; I just don't know how to 
"address" that menu item, as I don't manage it - web2py does - 

How would I accomplish this? ...
