That's not a problem just for IE. It's a problem that browser vendors could only solve by giving us WeakMaps (which could come in ES6 http://wiki.ecmascript.org/doku.php?id=harmony:weak_maps#wea... )... The problem is, you have a bunch of subviews which are registering events on some collection models... when you rerender your parent view your subviews get recreated but your previously created subviews stay in memory because the backbone events system still stores references to the old views which aren't really needed anymore. The only solution is to explicitly remove the events when subviews a destroyed (or better use a solution like in the submitted article) or use a library like https://github.com/marionettejs/backbone.eventbinder |
