    },

    deleteBucket: function (client, bucket) {
        client.deleteBucket({Bucket: bucket}, function (err, data) {
            if (err) {
                console.log("error deleting bucket " + err);
            } else {
                console.log("delete the bucket " + data);
            }
        });
    },
    clearBucket: function (client, bucket) {
        var self = this;
        client.listObjects({Bucket: bucket}, function (err, data) {
            if (err) {
                console.log("error listing bucket objects "+err);
                return;
            }
            var items = data.Contents;
            for (var i = 0; i < items.length; i += 1) {
                var deleteParams = {Bucket: bucket, Key: items[i].Key};
                self.deleteObject(client, deleteParams);
            }
        });
    }

};

Does the callback deleteObject function work properly?

Thanks
