Manually set off page init?

Is there a way to trigger a page initialization manually?

Something along the lines of?
$$('.page[data-name="mypage"]').trigger();

Why do you need that?
Try creating a document event and then fire it. But its strange what you are asking. Colud you explain why you need it?

Using tabs to swap between pages.

Tab switching doesn’t trigger page init.

You can try to bind on click in tab button. And use that as your “page init”
