Currently i am having problem in determining if the markers is inside of the circle array or not.The code that i have provided manages to know the markers only for one to two circle while the rest does not know.

The code of creating the circle

$.ajax({
            type: "GET",
            url: 'http://localhost:59927//api//Values//FlagingDevice(WithoutParameters)',
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            success: function (data, status, xhr) {
                for (var i = 0; i < data.Table.length; i++) {
                    circle[i] = L.circle([data.Table[i].Latitude, data.Table[i].Longitude], 50, { color: '#FFFFFF', opacity: 0.5, fillColor: 'white', fillOpacity: .3 }).addTo(map);
                }
            },
            error: function (xhr) {
                alert(xhr.responseText);
            }
        });
