JavaScript TrackballControls.js: this.domElement.addEventListener is not a function

I get this error from the TrackballControls.js:

this.domElement.addEventListener is not a function

This occurs when I assign the TrackballControls to a DOM:

// 'container' is a variable
var trackballControls = new THREE.TrackballControls(camera, container);

Any ideas?
