title: Trigger the event when selected the same value in dropdown?
body: <p>Issue: I have a dropdown with a list of years in it with nothing selected, the user selects "1976", I run a function. If the user clicks on the dropdown again and selects "1976" AGAIN, I want to run the function again.</p>
  
  <pre><code>$('select').on('change', function (e) 
  {
  var optionSelected = $("option:selected", this);
  var valueSelected = this.value; 
  alert(valueSelected);      
  });
  </code></pre>
