title: Handle event when Label Text Change
body: <p>I'm developing App which communicate with RFID Reader, I have the following Label which takes it's value from the Reader (when I click on the read button on the hardware)</p>
  
  <pre class="lang-XML prettyprint-override"><code>&lt;Label Text="{Binding Statistics.TotalUniqueCount}" /&gt;
  </code></pre>
  
  
  
  <p>I want to handle and event when the text value changed, it looks like the label doesn't has such event, is there any text view control that can handle the text change event? I tried to use Entry control, but the problem that when I read the RFID tags, it gives me the first and second time correct values, but the third time it gives me wrong value , and that's happens only when I use Entry.
  for example, I read 3 unique tags, it gives me first time 3, when I read more 2 tags, the number becomes 5, but when I read the third time another 3 tags, the number becomes 1.
  I put Entry and Label in the same page with the same Binding, the Label shows correct values and the Entry shows wrong values.</p>
  
  <p>is there any solution to handle event when this binding (Statistics.TotalUniqueCount) changes?</p>
