Unsubscribe object from another script

[CzarnyLewis]

When I subscribe object and then unsubscribe in one script everything is working.

on({id:"0_userdata.0.VIS.Views.LColorChange.RGB"}, function (obj) {console.log("OK")});
console.log(unsubscribe("0_userdata.0.VIS.Views.LColorChange.RGB")); //this line give me true

but then I move last line to another script I have the false response. Example:

Script1:
on({id:"0_userdata.0.VIS.Views.LColorChange.RGB"}, function (obj) {console.log("OK")});
Script2:
console.log(unsubscribe("0_userdata.0.VIS.Views.LColorChange.RGB")); //this line give me false

How to unsubscribe object subscribed in another script?
