body: <p>source code: <a href="https://jsfiddle.net/8pma5hr4/2/" rel="nofollow noreferrer">https://jsfiddle.net/8pma5hr4/2/</a></p>
  
  <p>I'm using <code>jquery autocomplete</code> for my <code>search box</code> when I giving an input, it is showing suggestion matching that input, after that I cleared the input using <code>my clear search icon</code>, after that if I'm <code>giving the same input</code> again, it doesn't show any <code>suggestion box</code>, I'm confused that why it is not working, please help me to solve this issue.</p>
  
  <p>Steps I did:</p>
  
  <ol>
  <li>In the search box, given the input " <code>s</code> "</li>
  <li>suggestion box shows with two values "<code>first</code>", "<code>second</code>".</li>
  <li>selected one of the options, after that clicked on that <code>x icon</code> to clear the search. (this icon will be at the end of the search box)</li>
  <li>after that, again given the same input "  <code>s</code> ".</li>
  <li>now the suggestion box is not showing (<code>this is the issue</code>)</li>
  </ol>
