MVC :: Mvc 3 : How To View Containing Partial View With Form

I have an Index view that shows a list of employees and a Create partial view with a form and submit button to create employees. In the Index view, I have:

@{Html.RenderAction("Create");}


A user sees a blank form to create employees and a list of employees. After the user has typed data in the form and clicked the submit button, the form should become blank and the list of employees should be refreshed, showing employees plus the new employee.

The problem is I don't know what to return from the Create action:

public ActionResult Create(Employee employee)
{
return ???
}
