Not able to Assert Object Property - Does proxyquire inject objects or just required modules?

Using Node, Sinon, and proxyquire.

I am trying to assert lock.normalAlert boolean value.

I am not able to assert the correct value...I only get the initial stubbed value.

Is proxyquire able to inject objects or just modules? I wasn't sure if the issue was injection.

test:

  sandbox = sinon.sandbox.create();

  var lock = require('../alerts').lock;
  sandbox.stub(lock, 'normalAlert', false);

  var alerts = proxy('../alerts',
                     {'node-fetch': fetch,
                       'lock': lock
                     });

  alerts.normalAlert('light', 1)

  lock.normalAlert.should.be.true;

code:

function _setNormalAlertLockout() {
  if (!lock.normalAlert) {
    lock.normalAlert = true;
    console.log(lock.normalAlert);

    setTimeout(()=> {
      lock.normalAlert = false;
    }, NORMAL_ALERT_LOCKOUT_TIME);
  }
}

module.exports = {
  lock: lock
}
