Auto-complete-input not working correctly with data binding

It works well but have minor issues in data binding.

How to replicate in status textarea

1. Type Hi :fire
2. It shows auto-complete with emojis. Select one by pressing Enter
3. Submit
4. Status submitted was Hi :fire - it had to be Hi :fire_engine:

When you type more text after auto-complete, it works properly.

Second issue is here: auto-complete-input doesn't bind back with empty text after submit
