[Zope] Replacing Documents or Methods contents

To replace contents of a Document or Method I tried this: <dtml-with target> <dtml-call "manage_edit('A new text', 'My new title')"> </dtml-with> where target is either a DTML Document or Method. It doesn't work in any case. No error message, but nothing seems to happen. Where am I wrong?
