ios - Remove event handler from memory (ortc) , titanium -

i have memory leak:

var ortc = require("co.realtime.ortc"); function ortcnot() { ortc.clusterurl = 'http://ortc-developers.realtime.co/server/2.2'; ortc.connectionmetadata = 'titanium example'; ortc.addeventlistener('onexception', function(e) { ti.api.info('exception: ' + e.info); }); ortc.addeventlistener('onconnected', function(e) { ti.api.info('connected ortc server'); ortc.subscribe('yellow24', true); }); ortc.addeventlistener('ondisconnected', function(e) { ti.api.info('disconnected ortc'); //remove event handlers //ortc = null; }); ortc.addeventlistener('onsubscribed', function(e) { ti.api.info('subscribed to: ' + e.channel); ti.api.info('sending message to: ' + e.channel); //ortc.send(e.channel, 'message iphone'); }); ortc.addeventlistener('onunsubscribed', function(e) { ti.api.info('unsubscribed from: ' + e.channel); ortc.disconnect(); }); ortc.addeventlistener('onmessage', function(e) { ti.api.info('message received: ' + e.message + ' @ channel: ' + e.channel); //parse message var message = json.parse(e.message); alert(message.user.message); //check chat id if (message.id == args.chatid) { recievemessage(message); } //ortc.unsubscribe(e.channel); ti.api.info(ortc.isconnected()); }); ortc.connect('yellow2'); } ortcnot();

when close controller window, reopen window. old event listeners still in memory, causing duplicate event listeners created.

any thought why happening,and how solve it? thanks

instead of defining listeners in-built function, declare them calling function.

to remove eventlistener has identical in both addeventlistener , removeeventlistener, declaring function , assigning eventlistener gets around this. e.g.

var viewobject = null; function eventtodo(){ // stuff here ... viewobject.removeeventlistener('click', eventtodo); } function addlistener() { viewobject = ti.ui.createview(); viewobject.addeventlistener('click', eventtodo);  homecoming viewobject; }

when close window not calling removeeventlister why every time window opened events beingness duplicated. attach close event window object in question calls function remove eventlisteners removing them applications memory.
