        }
    });
});

when I click first dropdown, It is automatically show the second Dropdown.

Please help me out of this problem.

If you don’t know how to change the order on the server side, you must do it in the client.

From your description I gather the result is a JSON object with each item having Id and Name, and that you want to iterate them not by name, but by id.

Therefore I suggest the following change to your code:

if (response.Success) {
    $('#Roles').children().remove();

    var results = [];
    // Converting the JSON object into an array
    $.each(response.Roles, function(index, role) {
        results.push(role);
    });

    // Sorting the array items by Id
    results.sort(function(a, b) {
        return a.Id - b.Id;
    });

    $.each(results, function (index, role) {
        $('#Roles').append(
            '<option value="' + role.Id + '">' +
                role.Name +
            '</option>');
    });
}

That should sort the resultset by Id before the items are added to #Roles.
