How do i pass the value calculated from autoform autovalue reactively?

Yeah, since this is an array of object the rendered html is

children.0.birthdate

so if the user add another child, it will be:

children.1.birthdate and so on.

I guess, I have to explicitly registered at least five change events.

I’ve tried children.[].age and ```children.[0,1,2,3,4,5].age, also no effect, ,

Is there a better way or approach to accomplish this?

The selectors are just css selectors so you can use starts with, ends with, and contains selectors just as you would in css

'change input[name^=children][name$=age]': function(event, template){
  //matches for name="children.#.age"
}
