Ember.js with a template

I would like to use Ember.js with a website template from Themeforest (with html, css and js files).

A problem with the main Javascript file from the template is that it is called only one time when the document is ready, but I would like to call it each time a user change his route.

For example, each time a new route is called, there is a new <div class="page-content"></div>, but the following jQuery line is not executed.

$('.page-content').wrapInner('<div class="page-content-inner"></div>');

Do you have any idea to solve this issue with a clean way? I don't want to change every line of the main Javascript file of the template that has about 1200 lines.

Thank you for your help
