Backbone.Validation.bind memory leak

[bigluck]

Hi everybody, I'm having memory leaks using Backbone.Validation.bind and unbind. If I bind a view and then, before destroy it, I unbind them:

class CountryEditView extends Backbone.View
    initialize: ->
        @parent = @options.parent
        @app = @parent.app
        @listenTo @model, 'change', @change
        @listenTo @model, 'destroy remove', @back

        Backbone.Validation.bind @,
            valid: (view, key) ->
                if ($ele = view.$("[name=#{key}]")).length
                    $ele.closest('.control-group').removeClass 'error'
            invalid: (view, key, error) ->
                if ($ele = view.$("[name=#{key}]")).length
                    $ele.closest('.control-group').addClass 'error'

    remove: ->
        Backbone.Validation.unbind @
        super

Even if the view has been removed using the remove() method, 3 references persist in memory:

• validate() backbone.validation-0.7.1.js:209
• isValid() backbone.validation-0.7.1.js:189
• preValidate() backbone.validation-0.7.1.js:182

Apologies for being a bit out of topic. What's the program you're using to analyse this issue?

I've used the Google Chrome Profiles taking Heap Snapshots
