Password strength not working

Hi,

I'm builing a new design using Foundation, but I've been having troubles with the password strength indicator. No matter what I type, the indicator just tells me to type a password...

I'm pretty sure this could have something to do with js, but I'm not sure. Anyone who got a clue?

I'm thinking the password strength isn't possible to show without BootStrap. Could I just make a stripped down version of Bootstrap and load in the pwstrength.tpl?
