Well you've only got one form, so when you hit submit all of the
item_id, quantity and price parameters are submitted and in this case
when faced with a repeated parameter rails picks the last one. The
browser doesn't know that because you've hit the submit button for one
row you only want to submit those fields that are close to it.
