Is there any reason why a camera's matrixworldinverse won't update when using trackball controls?

I'm viewing a scene using threejs and the trackball camera. I try to get the view matrix from the camera, but its matrixworldinverse isn't updating. I do call updateMatrixWorld in my render function. The matrixworld is updating, just not the inverse. Any ideas why?

You need to do it yourself:

camera.matrixWorldInverse.getInverse( camera.matrixWorld );

Make sure camera.matrixWorld is updated first. Note that by default, it is automatically updated by the renderer.
