Using an UICompleter does not work in interactive mode in the CLI

I have a UIInput where the end user should enter a class name for a Camel route builder class.

So I have a completer that implements the logic to find all route builders in the java source

routeBuilder.setCompleter(new RouteBuilderCompleter(facet));

And that only works from cli in non interactive mode, eg

[foo]$ camel-new-endpoint-routebuilder --componentName smtp --instanceName mail --routeBuilder com.foo.
com.foo.MyRoute  com.foo.YourRoute

When pressing TAB it shows the 2 route builder classes I have.

But in interactive mode the TAB does not work

Press <ENTER> to confirm, or <CTRL>+C to cancel.
? componentName (Name of component type to add): [0-180] 146
? routeBuilder (The RouteBuilder class to use):  co

I do not get any suggestions when pressing TAB.
