title: Detecting attribute change of value of an attribute I made
body: <p>I created an attribute in HTML <code>data-select-content-val</code> and it is stuffed with information dynamically.</p>
  
  <p>Is there a way to detect when the attribute's value has changed?</p>
  
  <pre><code>$(document).on("change", "div[data-select-content-val]", function(){
      alert("BOOP!");
  });
  </code></pre>
