I am using MVC+Angular. In MVC, I created partial views for search, listing, etc. I show them using:

@Html.Partial("_Search")
    
@Html.Partial("_Featured")
    
@Html.Partial("_Listing")

Previously each partial view had an ng-app and ng-controller.

Now I combined them all into one ng-app. I added ng-app to master page, and I just used the ng-controller in every partial view.

 <div ng-controller="Search" class="slide">
some ng-repeat goes here
</div>

Angular code:

angular.module("ProductListing", [])
.controller("Search", function ($scope,$templateCache, $http) {
    $(document).on("keyup", ".txtTempleSearch", function () {
        var searchTerm=$(this).val();
        $.get(configUrl + "SearchGrouped/" + searchTerm, function (data) {
            $scope.Results = JSON.parse(data)[0].result;
                $scope.$apply();
        });
    });
})
.controller('featured', function ($scope) {
    $.get(configUrl + 'Featured', function (data) {
        $scope.featuredTemples = data;
        $scope.$apply();
    });
})

Is this approach correct or is it better in terms of maintainability/performance/best practice to have a different ng-app for different partial views and use angular.bootstrap?
