使用ajax php的敲除数据绑定结果不起作用

我对knockout js很陌生,我正在尝试使用php ajax创建一个数据来自数据库的表。数据绑定不使用ajax php结果,而如果我在同一个页面中创建一个具有数据绑定变量的表,则它将使用表。如何我能让ajax结果与knockout一起工作吗。谢谢你的帮助 数据加载php:

include("db.php");
    $result=mysqli_query($conn,"select * from codes");
$par='\$parent';
echo '<table class="table table-striped box"  >
<thead>
<tr>
<td align=center> <b>Code</b></td>
<td align=center><b>Starting Date</b></td>
<td align=center><b>Closing Date</b></td>
<td align=center><b>Select</b></td></tr></thead>
';
 echo '<tbody data-bind="foreach:{data:rows,as:\'Row\'}">';
echo "<tr>
        <td data-bind='text:Row.codes'></td>
        <td data-bind='text:Row.sDate'></td>
        <td data-bind='text:Row.eDate'></td>
        <td align=center><button data-bind='click:$par.selectRow' class='btn btn-orange'>Select</button></td>
        </tr>";
while($data = mysqli_fetch_row($result))
{   
    echo "<tr >";
    echo "<td align=center data-bind='text:Row.codes'>$data[1]</td>";
    echo "<td align=center data-bind='text:Row.sDate'>$data[2]</td>";
    echo "<td align=center data-bind='text:Row.eDate'>$data[3]</td>";
    echo "<td align=center><button data-bind='click:$par.selectRow'  class='btn btn-orange addd'>Select</button></td>";
    echo "</tr>";
}
echo "</tbody></table>";

以及我的ajax代码:

$(document).ready(function(){
            $.ajax({
                type:"POST",
                url:"load.php",
                dataType:"html",
                success: function(response){
                    $("#codetable").html(response);
                }
            });
        });

还有我的击倒剧本

$(document).ready(function(){
    function Row(codes,sDate,eDate){
        this.codes=codes;
        this.sDate=sDate;
        this.eDate=eDate;
    }
     var myRowViewModel = new function(){
        var current= this;
        this.SelectedRow = ko.observable(null);
        this.rows=ko.observableArray([
            new Row("45sd9e","10-08-2018",1000),
            new Row("45sd9e","10-08-2018",1000),
            ]);
        this.selectRow = function(Row){
            current.SelectedRow(Row)
            alert(Row.codes);
        }
}
    ko.applyBindings(myRowViewModel);
});
