title: OnChange event not working in Input Type = Number when click on spinner in JQuery
body: <p>I have an</p>
  
  <p><code>&lt;input type="number" class="post-purchase-amount"/&gt;</code>. </p>
  
  <p>I am calling an
  ajax call when the value get changed. It is working (with the following code) when the cursor is in the
  text box itself and doing any changes. But it not working when i click the spinner (up/down button) of the input type.</p>
  
  <pre><code>parentPanel.on("change", ".post-purchase-amount", null, function (event) {
      updateAmount($(this));
  });
  </code></pre>
  
  <p>My problem is that i could use the "input" event here but that can call the ajax 
  every time when in change the value like if i want to send value 65
  then it calls twice when typing each number. I need to call ajax only when the value has been changed not every key
  stroke.
  Sorry for my English. Thanks in advance</p>
