function addNewManufacturer() {
    var name = $("#id-manuf-name").val();
    var address = $("#id-manuf-address").val();
    var phone = $("#id-manuf-phone").val();
    
    var sendInfo = {
        Name: name,

        url: "/Home/Add",
        dataType: "json",
        success: function (msg) {
            if (msg) {
                alert("Somebody" + name + " was added in list !");

            }
