Save values of HTML table to database in ASP.Net MVC using jQuery Ajax

I want to save all records from html table to the database without entity framework.

It actually saves the first row but ignores other rows.

Then, I also have some data in textbox that I want to pass to the controller as well, since I have passed table as JSON, how can I pass the values of the textboxes as well?

$('#btnsavetransaction').click(function () {
    //Loop through the Table rows and build a JSON array.
    var orders = new Array();
    $("#tblCart tbody tr").each(function () {
        var row = $(this);
        var order = {};
        order.Item_ID = row.find("TD").eq(1).html();
        order.Item_Name = row.find("TD").eq(2).html();
        order.salesPrice = row.find("TD").eq(3).html();
        order.Qty = row.find("TD").eq(4).html();
        order.Amount = row.find("TD").eq(5).html();
        orders.push(order);
    });
 
    //Send the JSON array to Controller using AJAX.
    $.ajax({
        type: "POST",
        url: "/Transactions/Transactions/InsertOrders",
        data: JSON.stringify(orders),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (r) {
            alert(r + " record(s) inserted.");
        }
    });
});
