MSFS Using events with index in JS

[eric_marciano]

Hello experts,
I would like to use a key event in my Javascript code. I know how to do this, it is easy. For example, to set the altimeter Kolhsman setting to 1013.25, you can do this:

SimVar.SetSimVarValue("K:KOLHSMAN_SET", "number", 16125);

The problem is that I have several altimeters, with index 1 and 2. If I use the line of code above, it sets ALL the altimeters to 1013.25. What if I want to set only one ?
The doc says a parameter is available for this:

KOHLSMAN_SET

[0]: Value to set [1]: Altimeter index

Sets altimeter setting (Millibars * 16).

In order to set altimeter #2 only, I tried this:

SimVar.SetSimVarValue("K:KOLHSMAN_SET:2", "number", 16125);

or this:

SimVar.SetSimVarValue("K:KOLHSMAN_SET", "number", 16125, 2);

Nothing works.

In XML I already did something like:

2 (>K:KOLHSMAN_INC)

or

2 (>K:KOLHSMAN_DEC)

This works, but today I want to do it in Javascript.

Any idea?
