title: React Async Select
body: <p>I am struggling with <strong>Async Select</strong> from <code>react-select</code>. I managed to display some defaultOptions and do an async fetch of its options using promises and <code>loadOptions</code> prop. </p>
  
  <p>What I need is to have the options updated (resolve the promise) when the dropdown of options is displayed on click. Is there a way to execute the same promise <code>onClick</code> (even in <code>onChange</code>)?</p>
  
  <p>I am using the following codepen provided by <code>react-select</code> team <a href="https://codesandbox.io/s/7w4w9yyrmx?module=/example.js" rel="noreferrer">https://codesandbox.io/s/7w4w9yyrmx?module=/example.js</a></p>
  
  <p>Thank you for your help!</p>
