I have found it myself in template name has to be renamed to $adonify.
@fhaps Thanks for your advice, but i am developer not consumer , so therefore 3d party plugin solution is not what i am after, i could simply use $('#billing_email').before( '<h3>Some Text</h3>' ); jQuery to add the headings , i wanted to implement it using php template generation, regardless , i. tried plugin demo and it does not have heading option anywhere, other way i could do is create input field and display only label of it , and target css for it to make it heading-like , which i want to avoid also , cheers for advise though!
