Can exports property be set to object instead of function?

I'm modularizing my client-side JavaScript code with Browserify.

In my "page" module, I'm trying to export an object with methods, like so:

// page.js

exports.picker = {
    init: function () { ... },
    getValue: function () { ... },
    // etc.
};

However, in another module, when I try to use one of these methods, I get a TypeError:

// other module

var page = require('./page');

// later...
page.picker.init(); // throws "TypeError: page.picker is undefined"

Not sure what I'm doing wrong. Is it maybe because I'm exporting an object instead of a function?
