Using bootstrap-modal as Backbone.js view


I am attempting to create a Backbone.js view based on a Twitter bootstrap-modal, which makes use of Backbone's automatic event delegation via the events attribute of the view.



Unfortunately, bootstrap-modal seems to break Backbone's event delegation as it clones the view HTML before displaying the modal:




that.$element
.appendTo(document.body)
.show()



My view:




App.Views.ProjectsNav ||= {}

class App.Views.ProjectsNav.NewProjectView extends Backbone.View
events: {
'click .save': 'save',
'shown': 'shown'
}

save: (e) ->
...
false

shown: () ->
App.Helpers.Forms.setFocus($(@el), true)
false

render: () ->
$(@el).html(ich.nav_edit_project_template(@model.toJSON()))
@$('.modal').modal({'show': true, 'keyboard': true, 'backdrop': true})
@



The corresponding (Mustache) HTML template:




<div class="modal hide" style="display: none; ">
<div class="modal-header">
<a href="#" class="close">×</a>
<h3>New Project</h3>
</div>
<div class="modal-body form-stacked">
<label for="name">Name</label> <input type="text" name="name" value="{{name}}"/><input type="hidden" name="lock_version" value="{{lock_version}}"/>
</div>
<div class="modal-footer">
<a href="javascript:void(0)" class="save btn primary">Create</a>
<a href="javascript:void(0)" class="cancel btn secondary">Cancel</a>
</div>
</div>



Neither save nor shown are called when the respective events are triggered.



Any ideas?
