Problem with ajax loaded page

When trying to use jplayer with page loaded through ajax i am getting the following error:

Uncaught TypeError: Cannot read property 'files' of undefined
at Object.Drupal.jPlayer.setFiles (eval at globalEval (jquery.min.js?v=2.1.4:2), :173:50)
at HTMLAnchorElement. (jplayer.js?pim57s:104)
at HTMLAnchorElement.dispatch (jquery.min.js?v=2.1.4:3)
at HTMLAnchorElement.r.handle (jquery.min.js?v=2.1.4:3)

When looking in the code everything seems fine in the html all the players are correctly loaded and the files are there but when i click on one of them to make it play I get that error.
