title: Underscore template not rendering in backbone
body: <p>I'm trying out a simple example (see full code below) with the latest production versions of backbone.js, underscore.js and jquery.
  However I can't get anything displayed on the screen. I have tried logging this.$el to console log and it seems valid, also the html var contains the correct parsed HTML from the test-template. But nothing is shown in the browser window.</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;meta charset="utf-8"&gt;
      &lt;title&gt;testing Backbone.js&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
  
        &lt;script type="text/template" id="test-template"&gt;
        &lt;div id="container"&gt;
            &lt;%= test %&gt;
        &lt;/div&gt;
        &lt;/script&gt;
  
        &lt;script type="text/javascript" src="js/lib/jquery.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript" src="js/lib/underscore.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript" src="js/lib/backbone.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript"&gt;
          var testView = Backbone.View.extend({
              el: $("#container"),
              template: _.template($('#test-template').html()),
              render: function() {
                  var html = this.template({test: 'hello World!'});
                  this.$el.html(html);
                  return this;
              }
          });
  
          $(document).ready(function() {
              var test = new testView();
              test.render();
          });
        &lt;/script&gt;
    &lt;/body&gt;
  &lt;/html&gt;
