Magnific popup: Get current element in callback

Question

In Magnific Popup, I want to get an attribute in the link that is clicked and use it in a callback function (using callbacks: open) to make some changes in the DOM.

How can I do this? For example, in the code below, it should return 'it works' to console. Instead it prints 'doesnt work'. Please help!!

<a href="#test-popup" class="open-popup-link" myatt="hello">Show inline popup</a>

<script src="jquery.magnetic.custom.js"></script>

<script>

    $(document).ready(function() {
      $('.open-popup-link').magnificPopup({
        type:'inline',
        midClick: true,
        callbacks: {
          open: function() {

            if ($(this).attr('myatt')=="hello") 
            { 
              // do something 
              console.log("it works");
            }
            else
            {
              console.log("doesnt work");
            }

          },
          close: function() {

          }
        }

      });
    });

</script>

<div id="test-popup" class="white-popup mfp-hide">
  Popup content
</div>
