Autocomplete value remains the old when entered text changed

[mustiy]

Describe the bug

It's about the Autocomplete Component.
If you select a value from the List, the selected value(NgModel) and the
value of Autocomplete Component ist [object Object]. That's ok.

But when i delete the value from the Component, value of Autocomplete remains
the old selected Value. I expected that the value is also cleared.

My purpose is to check if a value is selected from the list. I can not achieve this with NgModel.
