Just for other people that may end up at the same situation, in my case
here I mitigated it with events.
In my youtube case the time when the player is available is actually some
point in future after the elements are rendered, so what I did was to
create a new event `on-player-ready`, so at the parent I listen to that
event and capture the player instance (in this case, not the ref, but the
direct Youtube iFrame API player object), so that way I can work on the
player operations.
But would still find useful to know a way to capture a reference for an Om
built element somehow.
Thanks.
