  <pre><code>      console.log('+++ Kill: ', this);
          this.model.unbind( 'change', this.render, this ); // Unbind reference to the model
          this.options.parent.unbind( 'close:all', this.close, this ); // Unbind reference to the parent view     
          delete this.$el; // Delete the jQuery wrapped object variable
