Button click, rendering back to the same page

Hi All,

Am having a lot of trouble trying to solve a very simple problem.

I have a button on my form which when clicked needs to do a quick calculation then returns back to the same page to show the result.

VIEW.

<%=button_to "How much could I potentially borrow?", :action => "newmortgagecalc" %>

CONTROLLER

def newmortgagecalc   * some calculations here *   render end

What do I need to render in the controller method to get back to the same page?

Thanks

Richie.

render :action => :same_as_the_view

but if th calculation is not persistend (wont be saved to the db), use a js function and make everything in the client side
