title: Backbone + Require + Datamaps : "Datamap is not defined"
body: <p>I'm new to Backbone.js and i'm using it for a data visualization, as a school project.
  I've implemented require.js after some weeks of work, following this tutorial: <a href="http://backbonetutorials.com/organizing-backbone-using-modules/" rel="nofollow">http://backbonetutorials.com/organizing-backbone-using-modules/</a></p>
  
  <p>I've reorganized my code then, but now i got an error that i'm not able to fix... I use Datamaps (<a href="http://datamaps.github.io/" rel="nofollow">http://datamaps.github.io/</a>) to create a world map. I passed the needed scripts in the require define() function, but i'm probably doing something wrong.</p>
  
  <p>Here is the code part which provide the error :</p>
  
  <pre><code>define([
    'jquery',
    'underscore',
    'backbone',
    'd3',
    'c3',
    'topojson',
    'datamaps',
    'jqueryui',
    'text!templates/map.html'
  ], function($, _, Backbone, mapTemplate){
  
       var MapView = Backbone.View.extend({
  
         el: $('.container'),
  
         initialize: function(){
           var _this = this;
  
           var map = new Datamap({ ... })
  ...
  </code></pre>
  
  <p>And the browser respond with "Uncaught ReferenceError: Datamap is not defined". 
  It was working before, and since i use require, it doesn't work anymore, i've probably missed a param or something else.</p>
  
  <p>I would appreciate some help on this ;)</p>
  
  <p>Thank you in advance!</p>
