Setting up "jj" to force normal state

Hello everyone, I've tried setting up the "jj" key combo to exit from insert mode in evil using key-chord, but it doesn't seem to work. I'm using the following snippet: (key-chord-define evil-normal-state-map "jj" 'evil-force-normal-state)

(key-chord-define evil-visual-state-map "jj" 'evil-change-to-previous-state) (key-chord-define evil-insert-state-map "jj" 'evil-normal-state) (key-chord-define evil-replace-state-map "jj" 'evil-normal-state)

Key-chord.el is loaded, and I get no errors when evaluating the piece of code above. However, when I test by entering Evil's INSERT mode and trying to exit it by quickly pressing "j" followed by another "j", it stays at --INSERT--. Any hints appreciated! - Marcelo.
