title: Issue with this.$el.find in Backbone framework
body: <p>I get am "TypeError: this.$el is undefined" in my backbone View.</p>
  
  <p>Here is my simple backbone view code</p>
  
  <pre><code>var tableViews = Backbone.View.extend({
      initialize: function() {
          console.log("initialized");      
      },
      render: function() {
          this.$el.find(".clgcrt").removeClass("hidden");     
      }
  });
  </code></pre>
  
  <p>I included "<a href="http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js" rel="nofollow">http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js</a>" url for my backbone.</p>
  
  <p>Is there any problem with above backbone version?</p>
