Execution of an individual cell programmatically from its own output button onclick event

````
from IPython.display import display, Markdown, clear_output
import ipywidgets as widgets
from ipywidgets import Layout

backbutton = widgets.Button(
description="Back",
disabled=False,
icon=''
)

def buttonclicked(_):
with buttonout:
clear_output()
# need code here to execute the current cell

backbutton.on_click(buttonclicked)
`````
This buttonclicked function is actually a python ipywidgets library button's onclick function. This is an ouput of an individual cell. I want to run the same cell once more when I click on this button and get the initial output result. How to do it programmatically from inside the buttonclicked function ?

The payload names no repository files or tests; start by reproducing the Python ipywidgets Button callback in a Jupyter Notebook and trace how the output area and current cell are represented. Done means defining a supported way to rerun only the originating cell from its output button, with its initial output restored.
