How to show value instead of options text in the button for selected options?

[markusd1984]

Is there a configuration option or can we use template button to show value of options instead of options text for selected options?

UPDATE: I found buttonText with reference to " names of the selected options if less than numberDisplayed options are selected."

Managed to make it work by using the below

 labels.push($(this).attr('value'));

instead of

labels.push($(this).html());
