this._id undefined in Meteor

Question

I am trying to set my selectedDocId upon routing to a page, but Meteor is throwing undefined . I am using an onBeforeAction in an attempt to store the id that is concatenated at the end of my url via /:id, but I can't get them aligned.

 Router.route('speaker', {
            path:'/speakers/:_id',
            template: 'speaker',
            data: function(){
                return Speakers.findOne(this.params._id);
            },

            onBeforeAction: function(){
                console.log('speaker route has run');
                Session.set('selectedDocId', this._id);
                //returns undefined
                console.log(this._id);
                this.next();
            }
        });

        Template.speaker.helpers({

            editingDoc: function(){
                return Speakers.findOne({_id: Session.get('selectedDocId')});
            }

        });

Instead of this._id, use this.params._id just like you did in the data hook.
