Here is my code for adding a new row. the data from getJSON also returns the min value that i have to set for Qty upon rendering but im not sure how to pass this to drawback. not even sure if drawback is the answer.

function UpdateTableView(e) {
        var posUrl = '@Url.Action("UpdateTableView","Invoice")';
        var tblCount = pDt.rows().count()+1;
        $.getJSON(posUrl, { id: e.id, productTypeId: $('#ProductTypeId').val() }, function (data) {
            if (!data) {
                return;
            }
            dtbl.row.add({
                "No": data.ArticleNo,
                "Description": data.DisplayName,
                "Price": data.Price,
                "Qty": 1,
                "SubTotal": data.Price
            }).draw();
            
        });
        
        $('#dgAddProduct').modal('hide');
        
    }//

here is my code for my init. The existing onkeyup function works. Note that it is like a POS type page. how can i render the min value to Qty.

var dtbl = $('#example').DataTable({
        paging: false,
        searching: false,
        info: false,
        ordering: false,
        language: {
            "emptyTable": "No product selected."
        },
        
        columns: [
            
            { data: "No",width:"20%" },
            { data: "Description", width: "40%" },
            { data: "Price", render: $.fn.dataTable.render.number(',', '.', 0, '₱'), width: "15%" },
            {
                data: "Qty", width: "10%",render: function (data, type, row) {
                    return '<input class="form-control hello" id="Qty" name="Qty"  type="text"  value = ' + row.Qty + '  >';
                }
            },
            { data: "SubTotal", render: $.fn.dataTable.render.number(',', '.', 0, '&#8369;'), width: "15%",className:'dtRight' },
            
        ],
        "drawCallback": function (settings) {
            $(".hello").on('keyup', function () {
                var $row = $(this).parents("tr");
                var rowData = dtbl.row($row).data();

                rowData.Qty = $(this).val();
                console.log(rowData.Qty);

            });
          
        }
    });
