Manually trigger "t.render" in Trello client library

Is there a way to force or trigger trello to call t.render in associated iframes.

Their docs say " You should make sure any logic that updates your UI in visible iframes with changes should live in or be triggered by t.render. Trello will re-call t.render whenever something changes that we think might be relevant."

Trello isn’t calling t.render often enough for me. Is there a simple way to force it? I couldn’t find an obvious method for doing that in client.js.
