Autocomplete value as user type?

hello, since the google places autocomplete input doesn’t work for me (noapikey error, maybe because the API key keeps deleting itself) I’m trying to get an address input autocomplete to work with HEREWeGo API by querying the user typed value, BUT it seems that the value of an autocomplete input stays empty until an option is selected, yet again, I won’t have any option list until the typed value get passed to the query.

I read this but couldn’t get it to work:

any help is appreciated!
