How to update an event in Google Calendar using javascript?

Question

I need to update the name of some Google Calendar events, once I get them through JavaScript. I only have the sample code which Google shows in their Google Developer site,

        /**
         *  Update an event
         */
        function updateEvent(eventId) {
            if (eventId) {  
                var eventToUpdate = gapi.client.calendar.events.get({
                    "calendarId": 'primary', 
                    "eventId": eventId
                });

                eventToUpdate.summary = $("#update-name").val(); //Replace with your values of course :)
                eventToUpdate.location = $("#update-location").val();
                eventToUpdate.description = $("#update-description").val();
                eventToUpdate.start = {
                    'dateTime': (new Date(2017, 04, 22, 8, 00, 00)).toISOString(), //2017-04-22 08h00m00s
                    'timeZone': 'Europe/Paris'
                };
                eventToUpdate.end = {
                    'dateTime': (new Date(2017, 04, 22, 9, 00, 00)).toISOString(), //2017-04-22 09h00m00s
                    'timeZone': 'Europe/Paris'
                };

                var request = gapi.client.calendar.events.patch({
                    'calendarId': 'primary',
                    'eventId':eventId,
                    'resource': eventToUpdate
                });

                request.execute(function(event) {
                    console.log('Event updated: ' + event.htmlLink);

                    //Action. Maybe refresh your events list ? :)
                });
            }
        }
