I wrote the below code

    configurator = get_component('configurator')
    if (device_id in _CONFIGURING):
        configurator.notify_errors(_CONFIGURING[device_id], 'Failed    to    register,    please    try    again.')
        return
    def insteon_switch_config_callback(data):
        'Handle    configuration    changes.'
        setup_switch(device_id, data.get('name'), insteonhub, hass, add_devices_callback)
    _CONFIGURING[device_id] = configurator.request_config(hass, ((('Insteon    Switch    ' + model) + '    addr:    ') + device_id), insteon_switch_config_callback, description=((('Enter    a    name    for    ' + model) + '    addr:    ') + device_id), entity_picture='/static/images/config_insteon.png', submit_caption='Confirm', fields=[{'id': 'name', 'name': 'Name', 'type': ''}])
