Customize wordpress plugin

HI I have a working wordpress site with a custom theme and everything is working fine. In my site I have several posts with some images and text - I have also added an [login to view URL] to each post that will narrate the text on each post. The audio plugin I'm using is "[login to view URL]" for wordpress: [login to view URL] There is only one thing missing and that is that I want to be able to use the (ended-event in shortcode) and let the [login to view URL] know that when a ([login to view URL]) file have finished playing it should automatically go to the next post. The job for the freelancer is to modify the plugin downloaded from the site above or modify my own [login to view URL] and make the (ended-event) work with shortcode. The project can be can be discussed in more detail if need be. When the project have been accepted and if demanded I will post my js.files. This is important Thanks
