title: jqueryUI autocomplete does not function
body: <p>I have an array with some data that I want to autocomplete in an input section on the HTML, kinda like predictive text. I'm using jqueryUI and following instructions as per <a href="https://jqueryui.com/autocomplete/" rel="nofollow">https://jqueryui.com/autocomplete/</a> (to do some tests) but the code doesnt work - the data doesnt autocomplete when I fill out the input, even though its set up like the example? Its basically being loaded in order of (I am calling Jquery locally and JqueryUI externally):</p>
  
  <pre><code>&lt;script src="jquery.2.1.4.min.js"&gt;&lt;/script&gt;
  &lt;script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"&gt;&lt;/script&gt;
  &lt;script&gt;
  $(function() {
  
    var locations = [
        "London",
        "Paris",
        "Moscow",
        "Melbourne"
        ];
    $("#start").autocomplete({
     source: locations   
    });
  
    });
   &lt;/script&gt;
  
   &lt;input type="text" id="start"  placeholder="From" &gt;
  </code></pre>
