what you should do in your post check is 

           bill_item = BillItem.objects.get(code = itemcode)

form = BillItem(request.POST, instance = bill_item)


This populates the form with the existing model instance and merges with 
the post data.  you then can run form.save() to persist the update to the 
db.
