Bugfix Rails compilation

[raphaeljoie]

When compiling inside a Rails project I get :

function Plugin(element1, options) {
        this.element = element1;
        this.options = $.extend({}, defaults, options);
        this.globals = {};
        this.$container = $(element);
        if (this.errorCheck()) {
          this.init();
        }
      }

and I always get an "element is not defined" error.
