Weirdness with Lodash's _.bind and Superagent callbacks

_.bind.js

'use strict';

var lodash  = require('lodash'),
    request = require('superagent'),
    TestObj = {};

function asyncRequest (callback) {
    callback(null, {status : 'It works!'});
}

TestObj.foobar = 'bazquux';

TestObj.doFakeRequest = function () {
    asyncRequest(lodash.bind(function (err, res) {
        console.log('Errors', err);
        console.log('Status', res.status);
        console.log('FooBar', this.foobar);
    }, this));
};

TestObj.doSuperagentRequest = function () {
    request.get('http://example.com').end(lodash.bind(function (err, res) {
        console.log('Errors', err);
        console.log('Status', res.status);
        console.log('FooBar', this.foobar);
    }, this));
};



TestObj.doFakeRequest();
/*
Errors null
Status It works!
FooBar bazquux
*/



TestObj.doSuperagentRequest();
/*
Errors { ...contents of `res`... }

./test.js:24
        console.log('Status', res.status);
                                 ^
TypeError: Cannot read property 'status' of undefined
