Hi,

it looks like the changes have no visual effect but the state changes.

visual effect	log

I was running the example below

from bokeh.io import show, output_notebook
from bokeh.layouts import column
from bokeh.models import Button, DatePicker, TextInput, CustomJS
output_notebook()

date = DatePicker(title="DatePicker", value="2019-09-20")
text = TextInput(title="TextInput", value="2019-09-20")

# Bokeh button which disables the picker from python
button = Button(label="enable/disable")
button.js_on_event(
    "button_click",
    CustomJS(
        args=dict(date=date),
        code="""
        console.log(date.disabled);
        date.disabled = !date.disabled;
        """
    )
)
button.js_on_event(
    "button_click",
    CustomJS(args=dict(text=text), code="""text.disabled = !text.disabled;""")
)
show(column(date, text, button))

Works for me:

Let's make sure the JS resources are up-to-date, because this looks like a caching issue.

I have to apologize. Still can't reporduce the correct version on my maching but I added a log message and can't see the it.

Do you have "Disable cache" in devtools enabled? E.g.:

If so, then it's probably resources' resolution that's the problem. This may be known knowledge, but I will reiterate just in case. To make sure you use the most recently compiled resources, I strongly recommend running bokeh scripts with BOKEH_DEV=true BOKEH_RESOURCES=server-dev (which in bokeh 3.3 hopefully will be the default and thus reduced to just BOKEH_DEV=true) and then have BOKEH_DEV=true bokeh static running in a separate process/terminal.

@mattpap Thanks for your help. Now I get the expected result.
