Eclipse tries lazy loading of the plugins. So unless your plugin is
loaded, the updateElement of your handler won't be called. You can
probably extend org.eclipse.ui.startup to activate your plugin, which
should be done with care, as if affects the Eclipse startup performance.
What is your usecase?
