In many cases, I had to bind functions to ``this`` in ``componentDidMount`` and even once in the ``render`` function to get the binding to work. We SHOULD only need to make those calls in the constructor. I can't prove this, but I feel that it is a side-effect of us being a hybrid angular/react app while we are transitioning. So once we are a completely ReactJS app, we should move those ``bind`` calls to the constructor of the components.

We can also try using class properties, once we're on Neutrino 9: https://reactjs.org/docs/handling-events.html (search the page for "If you are using the experimental public class fields syntax")
