Using Facebook SDK in a mobile app

Content

I want to use the Facebook Javascript SDK in one of our mobile apps.  I cant do it the traditional way because the script tag is prohibted.  Should I create a new folder"js" under the resources folder, add the entire FB SDK locally, then reference that instead?  Also, is there a way to define an onload method in PageModule.  Something like

PageModule.prototype.onload = function(a,b,c) {

};

Submit button seemed to work by doing

PageModel.submit = function() {

};

Which overwrote the form submit action
