Suggest.js: Trigger change event when value is selected

[obenland]

Currently when the user selects a suggested value, the form element gets updated with the selected content, but only the focus event is triggered (and only if multiple values are allowed).
If the script is used in the context of the customizer for example, the preview doesn't get updated for the lack of information that an input value has changed.
