Backbone "Error: this._configure is not a function" - backbone.js

Question

problem with backbone. I'm new to programming with backbone
I have an error of "this._configure is not a function", but earlier versions of "backbone 0.9.2" and "underscore 1.4.1" works well, the problem does not run on ie9 so I want to pass to "backbone 1.0.0 "and" undercore 1.4.4 "and no longer works in any browser.
this is my code:
////////////// name of space
var doc;
var PDF = {
