AngularJS http post loop

How can I call the function once. When I do so, calling it loops. HTML: calling function from controller. find value of index.

    <body ng-controller="MainCtrl">
       <div ng-repeat="id in arr">
    {{sendPost(id)}}
      </div>
    <br>
        {{namestr}}
    </body>

JS: function request server for value

    app.controller('MainCtrl', function($scope, $http) {
    $scope.arr=[];
    $scope.arr.push(1);
    $scope.arr.push(2);
    $scope.arr.push(3);   
    $scope.namestr="";
    $scope.newName = "";
    $scope.sendPost = function(names) {
        $scope.namestr=$scope.namestr+' '+names;
        var data = $.param({
            json: JSON.stringify({
                name: names
            })
        });
        $http.post("/echo/json/", data).success(function(data, status) {
          //select from database
           if (data==1){
             return '1111'
           } else {
             return '2222'
           }
        })
    }                            
    });

This is bad idea in general

{{sendPost('Василий')}}

sendPost method and together with it http.post will be called with every single $digest process, and $digest is triggered by model change so this

$scope.hello = data;

will cause another $digest and another http request, explain more what you want to achieve and I'll extend your plunker
