How to initialize QTY +/- increment buttons (bricksWooQuantityTriggers())?

I am using a plugin (FiboSearch) on a Woocommerce installation, and it displays the add-to-cart button after finding a product. However, the +/- buttons do not work. The plugin developer states that because Bricks uses a custom function to initialize these buttons, any plugins (like his) that show the add-to-cart button with the standard WooCommerce method:

WC_Shortcodes::product_add_to_cart()

will have the same incompatibility.

How can I initialize the +/- buttons manually? Calling function bricksWooQuantityTriggers() did not work.
