How to trigger Ajax call after a box selection is done in python bokeh plot

I have two plots, namely, plot1 and plot2.

Plot2 has BoxSelectTool enabled and I can obtain point coordinates of the selected rectangular area using CustomJS.

Now I need to trigger an ajax call with the obtained coordinates to let server-side update plot2.

I posted the question at the StackOverflow:

It would be great if someone give me a help.

Thank you

I posted my own answer that solves using custom Event in JavaScript.
