The TreeView component uses OnPush strategy by default, which makes it unresponsive when the list is mutated. We will further investigate the case and will post an update soon.

I just like to inform you that we are preparing an enhancement in the TreeView directives that will support the described scenario. I'll update the thread once the fix is out.
