Finish simple ordering system in jQuery Mobile

We have a very simple ordering system for the restaurant business. This code is part of a complete hospitality system. The code we want should be written in jQuery Mobile (but if you think that there is a better solution then we are prepared to change it). It only consists of 3 pages : - enter name or table number - choose products - see order and send it We want to add some functionality like : - update orders before sending the actual order itself - add modifiers - add images when clicking on a product (if image is available) - change the look a little bit - ... This is a very simple project, but we will need more stuff in the near future. In attachment you have the code that is created now. The code should be changed or rewritten. Or if you should already have something that is working out of the box?
