Bind inputText with combobox

Good day

I know that you can bind combobox with a textfield but is it possible to do vice versa bind the view: “text” with a combobox ? So that when someone writes something in inputfield the combobox would show it in the list.

Here is what i have so far : Code Snippet

Right now the combobox gives an Error when i write anything in it.

The values can be selected by Id , is there a way to make it be selected by name ?

Maybe there is a way to sync the input field and the combobox input field ? So when i write something in the input it will be mirrored in the Combo.

Thank you for your time.
