Example of two autocompleters on the same page

I am having trouble getting 2 auto-completers to work independently on the same form. I used separate methods and variables for them both but when I select an option for the first autocomplete, that selection seems to be used as filter criteria that is applied to the second auto complete. Should I have two instances of " @ViewChild(MdbAutoCompleterComponent) completer: MdbAutoCompleterComponent;"?

Also, I am having issue getting the selected value committed to the form model. For example:

I would type "Acco" and then select the "Accounting" option. However, when the form is saved, only the value ("Acco" ) I explicitly typed is saved.
