Current behavior

I have added items to Autocomplete field, and when I delete an item, Model variable in the component is not getting updated.. issue similar to #213

Expected behavior

When an item is deleted from Autocomplete field, it should update the value array on the model side
Minimal reproduction of the problem with instructions

Add couple of items to Autocomplete field and print log of the Model variable in Component.. items are not delete in the value array

What is the motivation / use case for changing the behavior?
