I want to modify [plotly’s OncoPrint component](https://github.com/plotly/react-oncoprint) so that clicking a gene on the left triggers a prop update. I found that I can wrap the gene text [here](https://github.com/plotly/react-oncoprint/blob/master/src/components/OncoPrint.js#L131) with different HTML elements, but I’m unable to add an `onclick` to them to trigger a prop change. What would be the best way to do this?
