Perhaps you need to restart the infocenter.
Or, as you do below, let the infocenter know that
you have updated the set of plug-ins by calling the -apply (this is an
infocenter specific command). The update standalone support assumes you
are executing the commands on a stopped eclipse, and then the changes take
effect when you start eclipse.

The feature must first be deactivated (-command disable)
and then uninstalled (-command uninstall).
In both scenarios, you need to restart eclipse after
each command.

When using -update, make sure you specify the feature
id and version to update to.
