title: setAttribute not working
body: <p>I am making a plugin for form validation as practice, but for some reason after I create a h2 element and try to set it's attribute, it is not working. Here is the code</p>
  
  <pre><code>    var testing = function(regex, value, error_msg, error_msg_field_id){
          var pattern = new RegExp(regex);
          if (!pattern.test(value)){
              var ele = document.createElement("H2");
              var node = document.createTextNode(error_msg);
              ele.setAttribute('style', 'color:white');
              alert("hi");
              jQuery(error_msg_field_id).append(node);
          }
      }
  </code></pre>
  
  <p>the text appears with no problem, but it is not in white color. This make no sense at all to me</p>
