How to use a RadioButtonList and get the selected value with Ember?

I'm new to Ember and I'm doing an asp.net web api that's called using Ember and on a form I'm making I want to be able to get the value the user selected. How do I do this?

An example of one of the RadioButtonLists I want to use with Ember:

   <div class="form-group">
       <label for="nationalTransportation">3.1. NATIONAL TRANSPORTATION (*)</label>
       <div class="radio">
            <label><input type="radio" name="National Transportation" value="Not Required">Not Required</label>
       </div>
       <div class="radio">
            <label><input type="radio" name="National Transportation" value="Public Transportation">Public Transportation</label>
       </div>
       <div class="radio">
            <label><input type="radio" name="National Transportation" value="Own vehicle">Own vehicle (subject to approval)</label>
       </div>
       <div class="radio">
             <label><input type="radio" name="National Transportation" value="Car Rental">Car Rental (subject to approval)</label>
       </div>
   </div>
