How do I add new Video entirely from JavaScript?

I am trying to add a new VideoJS object and set it up entirely from JS, without having a DOM video element. The result is that the video is loaded but there aren't any VideoJS controls. Here is the code:

obj = document.createElement('video');
                $(obj).attr('id', 'example_video_1');
                $(obj).attr('class', 'video-js vjs-default-skin');

                var source = document.createElement('source');
                $(source).attr('src', path);
                $(source).attr('type', 'video/mp4');
                $(obj).append(source);

                $("#content").append(obj);
                _V_("example_video_1", {}, function () {
                    //
                    }
                });

I will appreciate any help, thanks!
