Work with elm and select : <p>I try to understand how elm works with a custom example.</p>

<pre><code>durationOption duration =
  option [value (toString duration) ] [ text (toString duration)]

view : Model -&gt; Html Msg
view model =
  Html.div []
    [ h2 [] [ text "Month selector"]
    , select []
      (List.map durationOption [1..12])    
    ]
</code></pre>

<p>It's an easy example to work with a select. I would like, each time I change the month value it multiplies to value by 10 for example. According to the documentation there is not events like <code>onChange</code> or <code>onSelect</code>, do I have to create mine with <a href="http://package.elm-lang.org/packages/evancz/elm-html/4.0.2/Html-Events#on">on</a> ?</p>
