title: Get value of radio checked in semantic ui
body: <p>I am trying to get the value of the checkbox after form is submitted, but nothing is being output. There is no documentation on how to do that on the website.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$(document).ready(function(){
      $('.ui.radio.checkbox').checkbox();
  
      $('#formOne').submit(e =&gt; {
         let num = $('#radio').val();
         console.log(num);
         e.preventDefault();
      });
  });</code></pre>
