Blazor, can't get embedded component to refresh

I realize this isn't a released product so I'm just experimenting, hopefully some of you came across a solution to the problem I am experiencing.

I have Component B included in Component A. When an item in a list is selected, Component B sees that and loads and displays the necessary data.

However, when I select another item from the combo list from Component A, it will not refresh component B's list and I guess that is because OnInitAsync is not called subsequently.

Does anyone have any solution?
