Delete chrome.alarms listener in chrome extension

In a chrome extension, it is very easy to create an alarm and add a listener to it with this sample code:

chrome.alarms.create(idAlarm, {
    when: dateAlarm,
    periodInMinutes: parseInt(repeatAlarm)
});
chrome.alarms.onAlarm.addListener(function (alarm) {
  //TODO with Listener (when alarm is activated)
)};

But, later, if I call 

crome.alarms.clear(idAlarm);

The alarm is cleared but the listener is still active. What is the best way to remove a listener for a specific alarm "on the fly"?

I presume I must call chrome.alarms.onAlarm.removeListener() but did not found a way to make this call works.

I'm definitely not an expert regarding chrome extensions (never wrote one), but looking at the docs I think you have to name the listener function and then do it like this:

function alarmListener(alarm) {
    if (alarm == "myAlarmIdentifier") {
        // Do stuff.
    }
}
chrome.alarms.create("myAlarmIdentifier", {
    when: dateAlarm,
    periodInMinutes: parseInt(repeatAlarm)
});
chrome.alarms.onAlarm.addListener(alarmListener);

Then to delete the alarm and remove the listener:

chrome.alarms.clear("myAlarmIdentifier");
chrome.alarms.onAlarm.removeListener(alarmListener);
