Product type and custom template

Hello, we used your plugin to add product bundles in the site above, the only issue is that the add to cart icon won’t display.
I tried to change product type to woosb on the code below from the template but nothing changed.

'add_to_cart_button' : '',
					esc_attr( $product->get_type() ),
					esc_attr( $product->get_type() == 'simple' && 'yes' === $ajax_add_to_cart ? 'ajax_add_to_cart' : 'swiper-no-swiping' ), // KiteSt codes
					esc_attr( $product->add_to_cart_text() ),
					esc_html( $product->add_to_cart_text() )
				),

Any ideas on how i can get it to display?
Best regards
