how to deploy image as a button in "pywebio"

Im trying to make an image button in "pywebio" module. I tried using "onclick" and I get this error message:

"AttributeError: 'Output' object has no attribute 'onclick'"

this is what I wrote:

img = open('homelogo.png', 'rb').read()

put_image(img, width='50px').onclick(print('d'))

does anyone succeed deploy image as a button?
