You need to add a relevant bash entry to `sh-imenu-generic-expression'.
I would propose a patch but the bash manual is vague about the allowed
characters, and I never use bash so I'm not interested in digging
further.  Maybe the newly added mksh entry could be a good example,

    (mksh
     . ((nil
         ;; function FOO
         ;; function FOO()
         ,(rx bol (* (syntax whitespace)) "function" (+ (syntax whitespace))
              (group (1+ (not (any "\0\t\n \"$&'();<=>\\`|#*?[]/"))))
              (* (syntax whitespace)) (? "()"))
         1)
        (nil
         ;; FOO()
         ,(rx bol (* (syntax whitespace))
              (group (1+ (not (any "\0\t\n \"$&'();<=>\\`|#*?[]/"))))
              (* (syntax whitespace)) "()")
         1)))

HTH.
