title: Can't access model attributes from Backbone View
body: <p>I'm walking into a large <code>Backbone.js</code> project so I'm still getting my bearings. My template, <code>my-group-item.jhbs</code> has:</p>
  
  <pre><code>{{#if isComplete}}
  .row-fluid
    .span2
      img.entity-image(src="/pictures/{{entityId}}.png")
  
    .span10
      .row-fluid
        .span12
          h3 {{entityName}}
          p My first variable {{totalFirst}} and my second variable {{totalValue}}
  
  {{/if}}
  </code></pre>
  
  <p>My <code>View</code> is:</p>
  
  <pre><code>module.exports = class MyItemView extends View
    className: -&gt;
      templateData = @getTemplateData()
      primaryData = @model.get('primaryData')
    tagName: 'li'
    template: require 'views/my-group-item'
  
    initialize: () -&gt;
      super
      primaryData = @model.get('primaryData')
  </code></pre>
  
  <p>In my template, the <code>totalFirst</code> and <code>totalValue</code> variables show nothing.</p>
  
  <p>I'm calling my view with:</p>
  
  <pre><code>  @groupView = new MyItemView
      collection: groups
      el: '.group-list'
  </code></pre>
  
  <p>How can I get these to show in the template?</p>
