add multiple items to quoteitem

[worldmiros]

In createView, I add a property, multiple: true, in createView. When I select multiple items, I get an error, "product.get is not a function" in the console. I ran iteration(for loop and/or foreach loo) in listentoonce, this.selectProduct(model[i]); ( or this.selectProduct(m)), but then I get error of "cannot set property 'checked' of undefined. I want user to add multiple items, but running an iteration in actionSelectProduct is not working. Appreciate any assistance you can give.
