Well, you need to separate the loop out from your component, so you
probably want something like

<div sea:id="question/questions">
  <page sea:id="pane"></page>
</div>

(or if you don't like having the <div>s that will create, use the <repeat>
tag which won't show up as anything).

Then you want something like

(template elementNamed: 'pane')
  class...;
  set: #theQuestion toPath: 'question'

The path there is referencing the local "question" variable created for
that repeat.

Make sense?
