title: Handlebars each not working
body: <p>So I have an array returning from the function call @mappingFunctions.getFunctionNames(), and I'm passing it into a handlebars template, but nothing's happening. </p>
  
  <pre><code>    @$el.append(@template({
        column: columns
        functionNames: JSON.stringify(@mappingFunctions.getFunctionNames())
      }))
  </code></pre>
  
  <p>In another file -</p>
  
  <pre><code>  getFunctionNames: -&gt;
      names = []
      functions = @get('functions')
      for name of functions
        names.push(name)
      return names
  </code></pre>
  
  <p>It seems like the each is not being run -</p>
  
  <pre><code>&lt;select class="map-columns"&gt;
    {{#each column}}
      &lt;option value="{{ this }}"&gt;{{ this }}&lt;/option&gt;
    {{/each}}
  &lt;/select&gt;
  
  &lt;select class="map-functions"&gt;
    {{#each functionNames}}
      &lt;option value="{{ this }}"&gt;{{ this }}&lt;/option&gt;
    {{/each}}
  &lt;/select&gt;
  </code></pre>
  
  <p>Why?</p>
