I have read through this question:
[What's the command to "reset" a bokeh plot?](https://stackoverflow.com/questions/39278110/whats-the-command-to-reset-a-bokeh-plot)

Which is close to what I'm trying to do. Except I'm trying to use an HTML button and have the JavaScript reset the bokeh plot, rather than creating a button in Python and tying the JS Callback to that python button. How can I pass the reference of the bokeh plot up to the javascript?
