Describe the bug

I'm encountering an issue where a Gradio app's Radio button component stops responding to user input after its choices are updated dynamically. Here's a breakdown of the problem:

Steps to reproduce

Create a Gradio app with a Radio button component and some initial choices. Include a function that displays a notification based on the selected radio option. Write code to dynamically alter the choices in the Radio button component. Try selecting a radio option after the choices have been updated.

Expected behavior

The notification function should execute, displaying the newly selected value.

Actual behavior

No notification appears, and the Radio button appears unresponsive.

Reproduction

import gradio as gr

def select_llm(llm_name):
    gr.Info(f"Selected {llm_name}")

def update_llm_select():
    return gr.Radio(choices=["LLaMA", "Gemma", "Grok", "Phi"])

with gr.Blocks() as demo:
    radio = gr.Radio(choices=["Claude", "DialoGPT", "GPT-3", "MegaM", "Mitsuku", "Replika", "Simsimi", "Sofia", "Zo"])
    update_radio_btn = gr.Button("Update")

    radio.input(select_llm, radio, [])
    update_radio_btn.click(update_llm_select, [], [radio])

demo.queue().launch()

Screenshot

The reproduction code will pop a notification containing the user-selected value.

But if you update the choices of the radio group, it breaks; nothing happens after the user's action, nothing is executed.

There were no warnings or errors in either the Python console or the browser's JavaScript console.

This should work with the select event @GaiZhenbiao - but I think we can fix the issue with the input event.

Hi @GaiZhenbiao! Thanks for raising this. I'm not sure if I'm able to reproduce this. Here's a recording on my end:
