I have `cape-elisp-block` capf backend in org-buffer, and it only
works in code block, that's why I need the autocomplete.

I also need the `flyspell-mode` in org-mode, the `flyspell-mode` will add
ispell-completion-at-point to capf, but when I input characters in
org-buffer, I don't need the ispell-completion-at-point backend.

Anyway, the below workaround works for me:

```
(add-hook 'text-mode-hook
          (lambda ()
            (remove-hook 'completion-at-point-functions 
'ispell-completion-at-point t)))
```
