Currently, I am facing an issue with the 'change' event of the Microform. The problem is that I created 2 fields 'number' and 'securityCode' and added an event listener 'change' on both fields. When I started to input or modify the value of the Card Number, I saw that the 'change' event listener on the field 'securityCode' was also triggered. This made me a little bit confused. Does any one know how to solve this issue?
