[2.0.0-rc4] ion-list (virtual scroll) become empty after remove 1 element


I just upgrade to rc4 then encounter this problem:
I have an ion-list which bind to [items] property (it’s value has 3 items):

It’s good, but when I remove 1 element of [items] property,

=> it becomes blank

Expectation: the list should display 2 items

Anyone encounter this problem like me ?
