python bokeh deselect data table rows

Question

I want to be able to "reset" a data table. How do I do that?

I have a defined an on_change('selected', my_callback) callback for my data table. The callback function has the following signature:

def my_callback(self, attr, old, new):
    ...

However I'm not able to deselect what has been selected after the my_callback handler is called.

I have tried to manipulate the new['1d'] or old['1d'] dictionaries without success.

What is the proper way to deselect rows in a data table and go back to the original state where nothing was selected?

There's a similar question on G-groups but it had no answers. Thanks

To deselect DataTable rows programmatically and go back to the original state where nothing was selected, you may use this in python:

source.selected.indices = []

where source is the ColumnDataSource for the DataTable.
