Baloon location on map is incorrect

Question

I put yandex map (russian analogue of google map) on my view. But but baloon's location does not match the coordinates!

Here is the code:

Example #1 - baloons display not correct

<script type="text/javascript">
    ymaps.ready(init);
    var myMap,
        myPlacemark;

    function init() {
        myMap = new ymaps.Map("map", {
            center: [55.76, 37.64],
            zoom: 10
        });

        @foreach (var person in Model)
        {
            <text>
        console.log('Service = @person.ServiceName, x = @person.CoordinateX, y = @person.CoordinateY');

        myPlacemark = new ymaps.Placemark([@(person.CoordinateX), @(person.CoordinateY)], {
            hintContent: '@(person.ServiceName)',
            balloonContent: '@(person.CoordinateX), @(person.CoordinateY)'
        });
        myMap.geoObjects.add(myPlacemark);
            </text>
        }
    }
</script>

But if I change it to constants (not in loop "foreach"), everything is normal:

Example #2 - baloons display correct

<script type="text/javascript">
    ymaps.ready(init);
    var myMap,
        myPlacemark;

    function init() {
        myMap = new ymaps.Map("map", {
            center: [55.76, 37.64],
            zoom: 10
        });

        myPlacemark = new ymaps.Placemark([55.871030, 37.658510], {
            hintContent: 'hint',
            balloonContent: 'content'
        });
        myMap.geoObjects.add(myPlacemark);

        myPlacemark = new ymaps.Placemark([55.782392, 37.614924], {
            hintContent: 'hint',
            balloonContent: 'content'
        });
        myMap.geoObjects.add(myPlacemark);
    }
</script>

NOTE: in Example #1 in console I get rigth values:

Service = something1, x = 55,87103, y = 37,65851

Service = something2, x = 55,782392, y = 37,614924

but baloon's location does not match the coordinates:

Incorrect baloons positions on map

Answer 1

We've found out that the problem was in the way ASP.Net outputs the numbers in the posted code snippets. They're printed into JS code with floating commas instead of points.
