hmmmm ... but how backend know if got any new transaction coming from the frontend? Does the backend have code to look for activity  OR frontend has code to pass info to backend or activate backend ?

Last time I did a simple form in html, I remember I had to specify an action in the form eg email to me any form submitted
*
From the code, it look like it passing the necessary info such as card number, cvv to backend. once u click the submit button, it will call a method and pass in the data to backend to continue the transation. Based on what you provided, i could not identify how it work.
