Backbone.js view not inserting template

Question

I am creating user views for my Backbone/rails application. I am attempting to add a new view:

/views/users/edit.js.coffee

class MosaikBackbone.Views.UsersEdit extends Backbone.View

  template: JST['users/edit']

  render: ->
    $(@el).html(@template())
    this 

The template is in /templates/users/edit.jst.eco

<h1>edit page</h1>

My router looks like this in /routers/users.js.coffee:

class MosaikBackbone.Routers.Users extends Backbone.Router
    routes:
        '': 'index'
        'users/:id': 'show'
        'users/edit/:id': 'update'

    initialize: ->
        @collection = new MosaikBackbone.Collections.Users()
        @collection.fetch()

    index: ->
        view = new MosaikBackbone.Views.UsersIndex(collection: @collection)
        $('#container').html(view.render().el)

    show: (id) ->
        alert "Entry #{id}"

    update: (id) ->
        editView = new MosaikBackbone.Views.UsersEdit()
        $('#container').html(editView.render().el)

The index views/templates work fine, and the view is being inserted into the container div. If I change the tagName for the UsersEdit view to 'li' I can see the li element in the DOM, it's just not being populated with the template. I'm guess it's a syntax issue but there are no errors in the console.

UPDATE: Just to clarify, the view is being appended to #container because i can see the empty element item, there is just an issue with rendering the template.

I refer to template: JST['users/index'] in my UsersIndex view and everything works fine. For some reason template: JST['users/edit'] isn't working even though both templates are in the same folder. Also, I can place invalid syntax in the edit template and no errors are thrown so it's not even being detected I dont' think

UPDATE 2: The following View/templates works without issue:

class MosaikBackbone.Views.UsersIndex extends Backbone.View

  template: JST['users/index']

  initialize: ->
    @collection.on('reset', @render, this)
    @collection.on('add', @appendUser, this)

  render: ->
    $(@el).html(@template())
    @collection.each(@appendUser)
    this

  appendUser: (user) ->
    view = new MosaikBackbone.Views.User(model: user)
    $('#users').append(view.render().el)

templates/users/index.jst.eco

h1>title here</h1>
<ul id="users"></ul>
