What is the best way to utilize ng-click for dynamically refreshing ng-repeat content?

On my webpage, I have implemented an ng-repeat directive. The initial loading of the page displays the data as expected through this directive. However, I am looking for a way to dynamically refresh the content of the directive using an ng-click function. Despite attempting various approaches, I am unable to achieve my desired outcome. Can anyone provide any suggestions or solutions?

<div ng-click="loadItems('1')">Load 1st set of items</div>
<div ng-click="loadItems('2')">Load 2nd set of items</div>
...

<table>
    <tr ng-repeat="item in items">>
        // stuff
    </tr>
</table>

ItemsCtrl:

$scope.loadItems = function (setID) {
    $http({
        url: 'get-items/'+setID,
        method: "POST"
    })
    .success(function (data, status, headers, config) {
        $scope.items = data;
    })
    .error(function (data, status, headers, config) {
        $scope.status = status;
    });
};

I attempted to utilize the loadItems() function in hopes that it would trigger the refreshing of the ng-repeat directive with updated data fetched from the server.

Implement a broadcast mechanism within your application to update data in real-time.

Consider moving this functionality to a service for better organization

itemsService.loadData = function (setID) {
    $http({
        url: 'retrieve-data/'+setID,
        method: "POST"
    })
    .success(function (data, status, headers, config) {
        $scope.dataItems = data;
        $rootScope.$broadcast('updateData', data);
    })
    .error(function (data, status, headers, config) {
        $scope.status = status;
    });
}; 

In the controller:

$scope.$on("updateData",function(d){
  $scope.dataItems = d;
});

Then, by using ng-click="refresh(id)"

$scope.refresh = function(id){
    itemsService.loadData(id);
}

Your dataItems will be automatically updated as it is subscribed to the broadcast channel.
