},
actionComplete: function (args) {
if (args.requestType === 'Links') {
if (args.elements[0].parentNode && args.elements[0].parentNode.tagName === 'A') {
var emberEle = document.createElement('blockquote'); // to add the link
emberEle.setAttribute('class', 'embedly-card'); // to add the class
emberEle.appendChild(args.elements[0].parentElement);
emberEle.appendChild(document.createElement('p'));
