I have enable smart-tab mode as global minor mode by

(global-smart-tab-mode 1)


and want to disable it in eshell-mode,

(add-hook 'eshell-mode-hook
	    '(lambda () 
            (smart-tab-mode -1)))

but It seems not work and I'm sure this hook have been executed.
If I manual run (smart-tab-mode -1) in eshell, It is OK.

I don't know why, could someone help me, thanks in advance!
