Hooks for entering and exiting Insert State in Evil

Hi, It seems to me that there are no hooks for entering and exiting Insert State in evil. So I'm doing the following workaround: (defadvice evil-insert ...) (defadvice evil-normal-state ...) The advice for `evil-insert' seems to be working but the advice for `evil-normal-state' was always being called even after entering Insert state. Can these hooks be added in evil? Or, is there any other mechanism for this? Thanks, York
