How to return ArrayBuffer from $http request in Node.js?

I sent a $http.post request from Angular.js to Node.js in order to get an ArrayBuffer as following:

$http.post('/api/scholarships/load/uploaded-files', Global.user, {responseType:'arraybuffer'}).success(function(ab){
    console.log(ab); // Return ArrayBuffer {}
});

Then, in Node.js, I retrieved uploaded files data and transform a Buffer object to ArrayBuffer object:

exports.loadUploadedFiles = function(req, res) {
    db.UserFile.findAll().success(function(files) {
        var buffer = files[0].dataValues.data; // Get buffer
        var arrayBuffer = new ArrayBuffer(buffer.length); // Start transforming Buffer to ArrayBuffer
        var views = new Uint8Array(arrayBuffer);
        for(var i = 0; i < buffer.length; ++i) {
            views[i] = buffer[i];
        }
        res.type('arraybuffer');
        res.send(arrayBuffer);
    }).error(function(err) {
        console.log(err);
        res.sendStatus(500);
    });
};

When I tried to print the response from above $http.post, I always got ArrayBuffer{}. What did I do wrong? Any help would be appreciated.
