Autocompletion Fire Onchange

This test verifies that on autocompletion the 'onchange' event is fired.

Steps to reproduce:

1. In the input field, type the word "apple" (without quotes). Then click the button Submit or hit the return/enter key on your keyboard
2. 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.
