Modelbinding when the model is repeated on the page

I can't believe this is so hard to find but...

I have a model that will be repeated multiple times on a page. By default it names the fields the same on both models so it doesn't seem to bind properly. How do I make it so I can use the same model multiple times?

Basic context of the issue: Picture having a user that can add unlimited contacts on the same page. The contact fields are based on a model (name address phone ect), and I just enumerate through that model to show each field for each contact. The first iterat开发者_StackOverflowion works fine, but after the first contact, nothing seems to get passed back to the model on post.

Thanks ahead of time.
