This test verifies that on autocompletion the 'onchange' event is fired.
Steps to reproduce:
  - In the input field, type the word "apple" (without quotes). Then click the button Submit or hit the return/enter 
  key on your keyboard
- Once the page reloads, in the input field, type "ap" (without quotes) and let the browser autocomplete the word (or select 
  "apple" from the autocompletion drop-down list contextual menu). Then click the button Submit or hit the return/enter 
  key on your keyboard.
