This is most likely due to rivets assigning the jQuery object to a local variable during its initialisation phase. This bug can be demonstrated here:

A simple fix would be to use window.jQuery instead of the local variable, as demonstrated here:

I am personally in favour of removing dependency on jQuery altogether, and letting the consumers override existing binders themselves.
