AngularJS doesn't work in MVC Partial Views

I'm currently working on a ASP.NET MVC project. The sites of the web application are created with Bootstrap. Later I added some AngularJS script to be able to translate the page into different languages. This works fine for all the pages, but not so if a partial view is loaded from a page. So, for example I have a page to search for rollout objects by name or host name. On the page all the angular expressions in curly braces are evaluated properly and are replaced with strings in several languages by using a translate script. Now if I filter the objects by one of the three attributes the partial view for that page is loaded showing the results of the search, but here are the angular expressions not evaluated and it just shows the expressions themselves.

Here is the page where it works properly:

@{
    ViewBag.Title = "{{ 'ROLLOUT-OBJECT_MANAGEMENT.TITLE' | translate }}";
}

<!-- html -->
<div style="font-size: 20px; margin-top: 20px;  margin-bottom: 20px;">
    <div class="gray-background list-group-item" translate="{{'ROLLOUT-OBJECT_MANAGEMENT.TITLE'}}"></div>
</div>
<div class="list-group">

    <div class="gray-background list-group-item">
        <div class="row margin-bottom">
            <div class="col-md-3">
                <h6 translate="{{'ROLLOUT-OBJECT_MANAGEMENT.FIRST_NAME'}}"></h6>
            </div>
            <div class="col-md-3">
                <h6 translate="{{'ROLLOUT-OBJECT_MANAGEMENT.SURNAME'}}"></h6>
            </div>
            <div class="col-md-3">
                <h6 translate="{{'ROLLOUT-OBJECT_MANAGEMENT.HOST_NAME'}}"></h6>
            </div>
        </div>

This is the _Layout.cshtml where the scripts are contained and loaded:

<body ng-controller="Ctrl">
  
  <!-- Here is the html for the navigation bar etc. -->
  
    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>

I am really not an expert on AngularJS as I only wanted to provide some cool translation feature, but I hope you guys have an idea why it doesn't work in the partial views.

Its just that you need to call the partial view using ng-include("'controller/action'"). Apostrophe(') is important while writing url.

Example

 <div id="TestDiv" ng-include="templateUrl"></div>

and inside the angular controller

 var app = angular.module("Layout", []);
    app.controller("LoadPage", function ($scope, $http, $sce) {

   //Initially
    $scope.templateUrl = '/Home/DefaultPage';

    // To dynamically change the URL.
    $scope.NewProjFn = function () {
        $scope.templateUrl = '/Home/ProjectPage';
    };
});

It might well not at all be difficult for you to re-implement it but by using ng-include you also need not to make an ajax call. It do it all by itself which includes ajax call, compilation and display. But the functions like ng-click and other events will not work as its a one time compilation process.
