Change cart button text to basket

Hello,

I have added below code supplied from the codex from the woothemes website

add_filter( 'add_to_cart_text', 'woo_custom_cart_button_text' );
function woo_custom_cart_button_text() {
return __( 'My Button Text', 'woocommerce' );
}

This works fine on the product pages but does not change the text on widgets and the basket (cart) page.

Does anyone know who to change the text in the widgets and basket page?

Any help much appreciated.

Thanks
