Subject: [PATCH] [FIX] website_sale: can't send coupon code after an ajax
 request

Before this commit, an user could only use the coupon form if he didn't perform
any ajax request (eg: change quantity, already sent a code..).
Since the cart html would be reinjected with theses ajax requests, the click
event would not work afterward until the page got fully reload.

Now, we changed the jquery click binding to work with dynamically injected DOM
