It works, but you have to click the "Create or adjust the cage" radio
button, then click back to "Deform the cage to deform the image". The
preview then updates.
Clearly a bug... or maybe a safety precaution. :)

Hello
It seems, cage transformation is broken in development version, at least
at commit 46296a264. Changing nodes positon does nothing, and
application of the tool does the same. The workaround is to change nodes
in deformation mode, switch to the creation mode and close the cage again.
