title: Attach onclick event to a dropdown with one element
body: <p>I have a dropdown. Initially it is empty and at some point it is filled with elements dynamically. When the user choose an option the onchange event is triggered. This works when there are at least two values in the dropdown.</p>
  
  <p>What I want to accomplish is, when there is only one element in the dropdown and the user clicks it, some event to be triggered. I tried the onclick event but this does not worked on the dropdown.</p>
  
  <p>Here is my jsfiddle:</p>

  <p>Some option may be to have defaut value like "Choose an option" in the dropdown and this way the onchange will always trigger. Is there are way to do it without this option?</p>
