title: How to track if input is being changed (jQuery)?
body: <p>I have the following code:</p>
  
  <pre><code>jQuery('#hexVal').change(function() {
      var hexvarval = jQuery('#hexVal').val();
      jQuery('#thumbnail_hover_color').val(hexvarval);
  });
  </code></pre>
  
  <p>Basically, I want to change value of <code>#thumbnail_hover_color</code> INPUT every time <code>#hexVal</code> INPUT is being changed. When I do it manually it works. When other jQuery script puts text to #hexVal then it doesn't update <code>#thumbnail_hover_color</code>.</p>
  
  <p>Question: How do I trigger "change value" for one INPUT field each time the value is changed (anyhow) in other INPUT field? I want them to have ALWAYS the same value.</p>
