How does asp.net MVC remember my incorrect values on postback?

Question

This is working, but how???

I have a controller action for a post:

[AcceptVerbs(HttpVerbs.Post )]
public ActionResult Edit(Person person)
{
   bool i

ModelState holds KeyValuePairs for every form element with the key being the field name and the value is what you put in the field. Then the Html Helpers look in ModelState and if you don't explicitly specify a value, they will pull the value from ModelState.
