Nested ItemViews, events not working properly - backbone.js

Question

I have 2 models, implemented via backbone.relational and backbone.localstorage, they're working good.
and I have 2 views, first is a "single item" viewer and the second one is an item view with a render function to view my single item view in the way I want, the problem is events not working, neither in parent view nor in single item view.
I've reimplemented that code in the similar way to show you how it's not working ( code is in coffeescript ) :
log = console.log
class $.Girl extends Backbone.RelationalModel
localStorage: new Backbone.LocalStorage 'gals'
initialize: -> if typeof #get('id') is 'undefined' then #save() else #fetch()
class $.Girls extends Backbone.RelationalModel
localStorage: new Backbone.LocalStorage 'gals'
relations:[{
type: Backbone.HasMany
key: 'gals'
relatedModel: $.Girl
includeInJson: 'id'
}]
initialize: ->
if typeof #get('id') is 'undefined' then #save() else #fetch()
#fetchRelated()
class $.GirlView extends Marionette.ItemView
tagName: 'tr'
template: (data)-> '<td>'+data.name+' -- '+data.age+'<button>Love</button></td>'
initialize: ->
#listenTo #model,'change',#render
events:
'click button': 'sayLove'
sayLove : -> log 'I Love YOU!'
class $.GirlsView extends Marionette.ItemView
template: (data)->
'<table>
<thead><tr><th>My Gals</th></tr></thead>
<tbody></tbody>
<tfoot><tr><td>I Love Them!</td></tr></tfoot>
</table>'
initialize: (options)->
#models = #model.get('gals').models
#list = []
self = #
_.each #models,(girl)-> self.list.push new $.GirlView {model:girl}
events:
'click th': 'hello'
render: ->
#$el.html(#template {})
self = #
_.each #list,(girl)->
girl.delegateEvents()
self.$('tbody').append girl.render().$el
hello: -> log 'hello'
gal1 = new $.Girl {name:'gal1',age:'22',id:'gal-1'}
gal2 = new $.Girl {name:'gal2',age:'19',id:'gal-2'}
gals = new $.Girls {title:'maGals',id:'gals-1',gals:['gal-1','gal-2']}
gv = new $.GirlsView {model:gals}
gv.render()
$('body').append gv.$el.html()
It's kinda hello world for me.
Any idea how can I implement nested itemViews with events working or any other idea for this snippet is appreciated.

Answer 1

Try calling delegateEvents after appending your child views:
self.$('tbody').append girl.render().el
girl.delegateEvents()
// or maybe #delegateEvents()? the context should be the child here
Edit:
Change $('body').append gv.$el.html() to $('body').append #$el.
