title: Select2 Copy values from one select2 to another
body: <p>I have a global select2 control, and when a button is clicked I would like to take the selected values and populate various other select2 controls with them.</p>
  
  <p>How do I add replicate the selected values from one select2 control to another?</p>
  
  <p>I have tried the following:</p>
  
  <pre><code>//Set Up control where values will copy to
  $(hashElement).select2({
              multiple: true,
              data: Details,
              initSelection: function (element, callback) {
                  data = $.parseJSON(element.val());
                  callback(data);
              }
          });
  
  
  var ApplyGlobalValues = function () {
          // get hashtag values 
          var values = $("#SelectGlobal").select2("val");
          $(".select-children").select2('val', values).trigger("change");
      }
  </code></pre>
  
  <p>The button fires ApplyGlobalValues() and initSelection is hit, but the values don't populate. What am i Doing wrong? </p>
