Deprecated {{view}} on Ember 2.0 - Rails 4

I recently updated a Rails 3.2 to Rails 4.1.0

I have the ember.js for data binding on it.

This is my Gemfile

source 'https://rubygems.org'

#gem 'rails', '3.2.12'
gem 'rails', '4.1.0'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails'
  gem 'coffee-rails'
  gem 'zurb-foundation'

# See http://ift.tt/MqZZdN for more supported runtimes
# gem 'therubyracer', :platforms => :ruby

  gem 'uglifier'
end

gem 'jquery-rails'

group :development do
  gem "better_errors"
  gem 'annotate'
  gem 'pry'
  gem 'sqlite3'
end

group :production do
  gem 'pg'
end

gem 'ember-rails'
gem 'ember-source'
gem 'handlebars-source'
gem 'active_model_serializers'
gem 'filepicker-rails'
gem 'execjs','2.5.2'
gem 'therubyracer'

gem 'thin'
gem 'unicorn'
gem 'capistrano'
gem 'simple_form'
gem 'devise'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

# File upload extension
gem "paperclip"

# Admin
gem 'activeadmin', '1.0.0.pre1'

I never had this deprecation issue before, when it was on Rails 3.2

Now every time I run the app it throws this error:

Barber::PrecompilerError at /
. Compiler said: Error: Assertion Failed: Using `{{view}}` or any path based on it ('_lineItem' @ L1:C0) has been removed in Ember 2.0

I'm fairly new to ember, so I'm kind of lost on this one.

It happened only after upgrading my Rails version.

This is the file in question:

_lineitem.hbs
{{#view 'lineItem' content='lineItem' class='row collapse'}}
<div class="name columns">
  <h6>{{lineItem.name}}</h6>
</div>
<div class="qty text-right columns">
  <h6>qty: {{lineItem.quantity}}</h6>
</div>
{{#if editing}}
  <div class="taxable columns text-right">
    taxable {{view 'checkbox' checked="lineItem.product.taxable"}}
  </div>
{{/if}}
<div class="line-total columns">
  <h6>
    {{#if editing}}
      {{input value="lineItem.priceCents"}}
    {{else}}
      <span class='money'>
        ${{money-display lineItem.lineItemTotalCents}}
      </span>
    {{/if}}
  </h6>
</div>
<div class="edit columns text-right">
  <button class="button small"{{action 'removeLineItem' lineItem target="view"}}>-</button>
</div>
{{/view}}

There's maybe some other file with this kind of declaration {{view}}

Please, any ideas?

Thanks in advance!
