How To Create A Helper That Is Going To Render A Partial View With A Model

I'll give a very simple example:

at the moment I have to write like this:

<% Html.RenderPartial("hello", new HelloInput { Name = "Jimmy" } ); %>

I would like to be able to like this:

<%=Html.Hello("Jimmy") %>

So I would like to know how create this helper:

public static string Hello(this HtmlHelper helper, string name)
{
return the result of rendering partial view "hello" with HelloInput{ Name = name };
}
