title: How to render a view when el was deleted?
body: <p>When the view is loaded during the first request, the collection is added to the view as desired:</p>
  
  <pre><code>    showMainpage: function() {
        console.log('show mainpage');
        var sidebar = new SidebarView();
  
        $("#maincontent").html(new SimpleItemsView().render().el);
      },
  </code></pre>
  
  <p>with SimpleItemsView:</p>
  
  <pre><code>  var SimpleItemsView = Backbone.View.extend({
      el: $("#overview"),
      tagName: "tbody",
  </code></pre>
  
  <p>However, when the DOM changes, and the part of the #maincontent changes, the #overview element can not be resolved anymore, see:</p>
  
  <p><img src="https://i.stack.imgur.com/ztl48.png" alt="overview disappears"></p>
  
  <p>How can I re-render the #overview part? The project is also here: <a href="https://github.com/mulderp/backbone-require-test/blob/master/public/js/app.js#L31" rel="nofollow noreferrer">https://github.com/mulderp/backbone-require-test/blob/master/public/js/app.js#L31</a></p>
