On quantity plus minus custom form appearing more then once

Hi,

I have created an custom business invoice form which comes just above payment sectio.
Used following action:

add_action(‘woocommerce_review_order_before_payment’, ‘business_taxinvoice_checkout_field’,10);

Function business_taxinvoice_checkout_field contains 4 input fields.
Now when I do plus/minus under cart’s product’s quantity section that business invoice section/form comes number of time as I click it.

Can any one tell what exactly I am missing or doing wrong?

Feedback appreciated..!!

Thanks
