modal dialog with backbone

1.html

<script id="modal-view-template" type="text/html">
  <div class="modal-header">
    <h2>This is a modal!</h2>
  </div>
  <div class="modal-body">
    <p>With some content in it!</p>
  </div>
  <div class="modal-footer">
    <button class="btn">cancel</button>
    <button class="btn-default">Ok</button>
  </div>
</script>

<div id="modal"></div>

2.js

var view = new MyView();
view.render();

var $modalEl = $("#modal");

$modalEl.html(view.el);
$modalEl.modal();

3.js

  var ModalRegion = Backbone.Marionette.Region.extend({
    el: "#modal",

    constructor: function(){
      _.bindAll(this);
      Backbone.Marionette.Region.prototype.constructor.apply(this, arguments);
      this.on("view:show", this.showModal, this);
    },

    getEl: function(selector){
      var $el = $(selector);
      $el.on("hidden", this.close);
      return $el;
    },

    showModal: function(view){
      view.on("close", this.hideModal, this);
      this.$el.modal('show');
    },

    hideModal: function(){
      this.$el.modal('hide');
    }
  });

4.js

var App = new Backbone.Marionette.Application();

App.addRegions({
  main: "#main-content",
  modal: ModalRegion
});

// somewhere else in the app
var view = new MyView();
App.modal.show(view);

I think line 5 of 3.js should be:

_.bindAll( this, "getEl", "showModal", "hideModal" );

otherwise, bindAll complains that it should be passed some function names.

I made a gist that worked for our current project with Bootstrap and Backbone 1.0 https://gist.github.com/insaciableslabs/6369107
