Correct.

Partly correct. You shouldn't use #show: or #call: for that matter
during rendering, only in callbacks.

Render doesn't answer anything because the result of rendering is
markup to display. Only when the user actually does something,
something can be answered. What you probably want is a task and #call:
the component.
