Thank you for your answer. Sorry for the time to reply.
I've finally reseted location and suspend_data in ScormWrapper.prototype.setPassed = function() {
in wrapper.js.
I've also modified ScormWrapper.prototype.setLessonLocation
and ScormWrapper.prototype.setSuspendData
that way:
if(this.scorm.data.completionStatus === "completed")
_data = "";
to be sure that bookmark will not be used anymore.
