title: Is there a way to display custom text for TextProperty? (JavaFX)
body: <p>Let's assume that I have a TextField and a Label</p>
  <pre><code>TextField customTextField
  Label customLabel
  </code></pre>
  <p>I want to bind the <code>customLabel</code> to the <code>customTextField</code>'s TextProperty. After doing so the <code>customLabel</code> will be updated according to what the <code>customTextField</code> contains. However,  I want something a bit more than this. For example, if I enter the amount <code>15.0</code> I want it to update the <code>customLabel</code>'s text to <code>15.0/100.0</code>. Is there any way of doing this?</p>
  <p>Thanks in advance.</p>
