Cannot change bash shell in Mac OS X

I'm trying to update bash shell on my Mac OS Mavericks. $ brew install bash $ which -a bash /bin/bash /usr/local/bin/bash $ which bash /bin/bash $ chsh -s /usr/local/bin/bash $ which bash /bin/bash In Terminal's preference: Shells open with -> Command (complete path) : /usr/local/bin/bash. But still, I cannot switch to brew-installed bash shell. What can I do?
