i need calculation if radio button has data price attribute.
you can use "has attribute" selector limit selection radio buttons attribute:
$('input:radio[data-price]').change(... side note: using jquery's css extensions not best practice, because as says in :radio api documentation, means jquery can't hand off browser's native handling. instead:
$('input[type=radio][data-price]').change(...
