External Javascript call in mobile player

I have a project in which I need to call to external javascript functions using the "javascript call" trigger. In order to achieve this I include a reference to the .js file in the story.html and story_html5.html.

Like this: <script src="js/desafioCasa.js" type="text/javascript"></script>

If I access the publication in a browser this works fine, but inside the articulate player for android or Ipad this won´t work. I imagine that the problem is due to the javascript functions I call inside the triggers are not found and I have to add the reference to the external js file somewhere else.... Any help is appreciated.

I tried to duplicate the js file inside the "mobile" folder and include the reference to this file inside the "mobileinstall.html" but without success.

Thanks in advance!
