title: Backbone Marionette: templateHelpers and itemViewOptions
body: <p>I've a problem with Backbone Marionette and ItemView rendering. 
  I need to pass a value from the Composite View to each of its Item View.
  The value is contained correctly in the options array of the Item View, however, I cannot access it from the templateHelpers method.</p>
  
  <p>So I tried to set it as value of my View but when I render the array it returns an "undefined" value.</p>
  
  <p><strong>The Composite View</strong></p>
  
  <pre><code>var TableView = Backbone.Marionette.CompositeView.extend({
  ....
      itemViewOptions: {
          foo: "bar",
      },
  </code></pre>
  
  <p><strong>The Item View</strong> </p>
  
  <pre><code>var RowView = Backbone.Marionette.ItemView.extend({
  
  template: RowTemplate,
  tagName: "tr",
  foo: "",
  
  initialize: function(){
  
      this.foo = this.options.foo;              
  },
  
  templateHelpers: {  
  
       foo: function(){
           return this.foo;
       }
  
  },
  </code></pre>
  
  <p>What I'm doing wrong? How can I access the value and fetch it to the template? Thank you.</p>
