xAPI Completion event

I'm not even able to test whether these values are set.

My code does not write to the console:

H5P.externalDispatcher.on('xAPI', function (event) {

                    var complete = event.data.statement.result.completion;

                    console.log(event);

                    console.log('hi');

                    console.log(event.data.statement);

                    if (complete == true) {

                        $("#edit-submit").fadeIn();

                    }

                });

There is no indication that the dispatcher is registering my listener or that the memory game calls xAPI events at all.  My testing consists of logging the EventDispatcher which has the on callback and is not undefined.  And then attempting to log to the console when completing a memory game in the listener.

When I paste

 H5P.externalDispatcher.on('xAPI', function (event) {
  console.log(event);
});

in the console, i get undefined and no further messages while working through the memory game.

thanks for continuing to work with me on this.  It's a drupal site, there are no iframes... infact when we do this with h5p video which uses iframes it works.

the full behavior looks something like this now (the console log 'registered' displays in console):

Drupal.behaviors.forceh5p = {

        attach: function (context, settings) {

            if ($('.quiz-question-node--h5p_content').length) {

                Drupal.behaviors.forceh5p.checkH5P();

                console.log('I checked h5P');

                if ($('.h5p-content').contents().find('.h5p-container')) {

                    $("#edit-submit").hide();

                }

                var id = $('.h5p-iframe').attr('data-content-id');

                $("#h5p-iframe-" + id).load(function () {

                    if ($("#h5p-iframe-" + id).contents().find('.h5p-content')) {

                        $("#edit-submit").hide();

                    }

                });

            }

        },

        checkH5P: function () {

          if (typeof H5P.externalDispatcher.on !== 'undefined') {

            console.log(H5P.externalDispatcher);

            Drupal.behaviors.forceh5p.registerH5P();

          }

          else {

            window.setTimeout('Drupal.behaviors.forceh5p.checkH5P();', 100);

          }

        },

        registerH5P: function () {

          console.log('registered');

          H5P.externalDispatcher.on('xAPI', function (event) {

              //var complete = event.data.statement.result.completion;

              console.log(event);

              console.log('hi');

              console.log(event.data.statement);

              var complete = event.getVerifiedStatementValue;

              if (complete === true) {

                  $("#edit-submit").fadeIn();

              }

          });

        }

    };

The submit button gets hidden but does not log console events while interacting with the question to indicate a means for showing the submit button when the question has been answered.
