How to use pn.bind with Button?

Panel
1 
import panel as pn
pn.extension()

def callback(event):
    return button.clicks

button = pn.widgets.Button()
counter = pn.bind(callback, button)
pn.Row(counter, button).servable()

Is this the best way of using pn.bind with Button?

Can you explain what you see as the problem with your code example?

If you want the clicks as input you could do this:

import panel as pn
pn.extension()

def callback(event):
    return event

button = pn.widgets.Button()
counter = pn.bind(callback, button.param.clicks)
pn.Row(counter, button).servable()

I would say both examples are fine. To start with pn.bind is the recommended api to use. Probably @Hoxbro example a bit better because it does not use the button inside the callback function. This makes it possible to separate the UI widgets and the functionality.

Yes that is exactly what I was looking for; the use of button.param.clicks for the reason that Marc stated.
