Intercept only change event triggered by the GUI

Hi,

I use JQuery query builder in a angular child component and I meet many troubles with events.

When I initialize the query builder before displaying on my web page, I get the JSON data which contains the definition of the rule (condition, filters, operator...). That is not the problem because everything works fine so far.

The problem is I want to intercept all modification performed by the user via the GUI and only these modifcations and not the modification brought by the set_rule method.

1. Do you know a mean so that setting rule with JSON (set_rule method) do not trigger afterCreateRuleInput event?
2. Does it exist a property on event handler parameters which allows knowing change origin (rule initialization via set_rule or user via the GUI)?
3. How to retrieve the new JSON data in the event Handler?

Regards
