title: How to bind TextField and String object in JavaFX?
body: <p>I have some words which I show in TextField. I want to rewrite this words every time when this words have been changed in TextField. 
  This is my type:</p>
  
  <pre><code>class WordType {
     String first;
     String second;
  }
  </code></pre>
  
  <p>and ListView where I show my words:</p>
  
  <pre><code>ListView&lt;WordType&gt; list = new ListView&lt;&gt;();
  
  list.setCellFactory(lv -&gt; new ListCell&lt;WordType&gt;() {
          @Override
          public void updateItem(WordType item, boolean empty){
              super.updateItem(item, empty);
              if (empty){
                  setText(null);
              } else {
                  ToolBar root = new ToolBar();
  
                  TextField word = new TextField(item.first);
  
                  TextField translate = new TextField(item.second);
  
                  root.getItems().addAll(word, new Separator(), translate);
                  setGraphic(root);
              }
          }
      });
  </code></pre>
