title: ember.js making your variables accesssable from childroutes
body: <p>i'm new at ember.js and i worked out the guide and read a lot of stuf. I've got a simple(?) problem, but i cant see the light :) </p>
  
  <p>So I try to programm a questionnaire. </p>
  
  <p>My idea is, i make the controll of the questionnaire on the mainpage (called kalkulator) and save the variables on this page too. Because at the last outline side i want to calculate the result.</p>
  
  <p>My question is saving the variables at the index the right strategy? </p>
  
  <p>I tried it, but i fail on the first side of my questionnaire, i cannot access at the variable from the mainpage kalkulator.</p>
  
  <pre><code>App.AgentverteilungController = Ember.Controller.extend({
  
      needs: "kalkulator"
  });
  
  
  
    &lt;script type="text/x-handlebars" id="agentverteilung"&gt;
        &lt;ul&gt;
          question...
            {{input type="text" value=kalkulator.variable size="4"}}
            Inserted: {{kalkulator.variable }}
        &lt;/ul&gt;
    &lt;/script&gt;
  </code></pre>
  
  <p>I hope somebody can help me.  Thanks for advices. </p>
