The problem is that $.title in title.mi is not the same $.title in index.mc…
They are different components, different object instances.

In title, you need to access $m->page->title…

I wrote a small proof-of-concept, you can find it here:

See how $self is a different instance inside title.mi and index.mc.

Yes, $m->page.
