AngularJS routes can't be recognized on manual refresh - ruby-on-rails

Question

Hi I followed a tutorial: http://omarriott.com/aux/angularjs-html5-routing-rails/
Here's my manual.js.coffee.erb
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/
#= require_tree ./templates
#Bento = angular.module('bento', ['ngRoute', 'ngResource', 'ngSanitize', 'ui.bootstrap', 'infinite-scroll'])
# Pre-cache templates
Bento.run ($window, $templateCache) ->
templates = $window.JST
for fileName of templates
fileContent = templates[fileName]
$templateCache.put(fileName, fileContent)
# Note that we're passing the function fileContent,
# and not the object returned by its invocation.
#= require_tree ./controllers
#= require_tree ./services
#= require_tree ./directives
My routes.js.coffee.erb
#Bento.config ["$routeProvider", ($routeProvider) ->
$routeProvider.when("/",
controller: "ActivitiesController"
templateUrl: "<%= asset_path('templates/user/activities.html.haml') %>"
redirectTo: (current, path, search) ->
if search.goto
"/" + search.goto
else
"/"
).when("/projects/activities",
controller: "ProjectAllActivitiesController"
templateUrl: "<%= asset_path('templates/projects/activities.html') %>"
redirectTo: "/example"
).when("/projects/:id",
controller: "ProjectCtrl"
templateUrl: "<%= asset_path('templates/projects/list.html') %>"
redirectTo: (current, path, search) ->
if search.goto
"/projects/:id" + search.goto
else
"/projects/:id"
).otherwise redirectTo: "/"
]
And lines that I added to my config/routes.rb file
match "api" => proc { [404, {}, ['Invalid API endpoint']] }, via: [:post]
match "api/*path" => proc { [404, {}, ['Invalid API endpoint']] }, via: [:post]
match "/*path" => redirect("/?goto=%{path}"), via: [:post]
Since I'm using rails 4, I need to add a via
# sign is adding whenever I refresh my root path localhost:3000/ but it's not working in nested URLs like localhost:3000/projects/1 it's still reading my routes for RAILS.
PS: Whenever i refresh localhost:3000/projects/activities for example, it's still reading my rails routes instead of going to localhost:3000/example.
