Make vs Make dev: Work differently

I use the development code (https://github.com/jitsi/jitsi-meet) > custom event kickout > code in the file “jitsi-meet/conference.js”

in the development environment: will run through the function “room.on(JitsiConferenceEvents.KICKED,…”

BUT

on the server environment: not call function “room.on(JitsiConferenceEvents.KICKED,…”

WHY?
Please help me.

Somebody Help me :(((((
