Memory leak when switching between views in knockout single page application

Question

My app consists of a shell view which loads sub views within it using knockout's templating engine. All the views are built on knockout.

When navigating between views, the value of an observable changes indicating that a new view needs to be bound to a template.

I've packaged the app into an exe using node webkit and it is apparent that RAM usage keeps increasing when I switch views. Memory is only released when the app is closed.

Any idea what red flags I should be looking out for in the code which may be causing this leak and what tools could help me pinpoint the issue?
