'color-activated' signal not emitting

[Craig Cabrey <craigcabrey@xxxxxxxxx>]

According to the docs [0], the "color-activated" signal is emitted upon

the user making any changes to the current color.

I'm having trouble with this signal in two scenarios:

1) When a GtkColorChooserWidget is inside of a GtkPopover [1, 2]

2) When a GtkColorChooserWidget is inside of a GtkWindow [3, 4]

I am not sure if I'm using GtkBuilder, signals, or pygobject
incorrectly. The signal is being picked up correctly, because

when I comment it out, GtkBuilder complains. However, even

when I change a color, nothing is fired (and yes, I put a quick

print statement in as a sanity check).

I am using GTK 3.20.6, Python 3.5.2, and pyobject 3.20.1 on Arch.

Any help or pointers would be greatly appreciated! This is my first

GTK project so I apologize if I'm missing something obvious.
