Rails - Jul 2007 - Events in view question

I have taken an example wherein, using Ajax, the values of a second
combobox are populated by a change in the primary combobox. The code
is shown below.

I realise it will seem as though I am asking someone to write the code
for me, BUT, can someone please show me, by way of an example how to
amend my index.rhtml below to use, say a radio button group instead of
a combobox, wherein when you change the radio button group, the
secondary combobox is changed, without having to incorporate a submit
button?

I somehow need someone to kickstart me here with this, and I can
bootstrap the rest of what I am trying to do. Thanks. R. Vince

#in mycontroller:

  def create_select
    indArr=["Nordic Skiing", "Inline
Skating","Tennis",
      "Triathlon","Road Racing","Figure Skating",
      "Weight Lifting","Speed
Skating","Snowboarding"];
   
teamArr=["Soccer","Basketball","Football","Hockey",
      "Baseball","Lacrosse"];
    str="";
    if params[:categories].index(''Team'') != nil
      render :partial => "options", :locals => { :sports =>
teamArr,:sptype => "team"}
    elsif params[:categories].index(''Individual'') != nil
      render :partial => "options", :locals => { :sports =>
indArr, :sptype => "individual" }
    else
      str="<select id=''individual''
name=''individual''>
           <option>unknown</option></select>";
      render :text => str;
    end
 end

      Please select a sports category:
