What can block the onclick event?

Question

JavaScript

There is a checkout form

I use the wordpress + woocommerce engine
The fact is that the change event inside the form works, but click does not

<form name="checkout" method="post" class="checkout woocommerce-checkout" action="<?php echo esc_url( <code 
wc_get_checkout_url() ); ?>" enctype="multipart/form-data">
//тут данные формы
</form>

Because of what it can be?

Answer 1

Probably because there is no "click" word in the form code...
