JQuery UI inline DatePicker loses selected date after ASP.NET postback, How to keep it?

Hello to All
I have a  jquiry datepicker and the code is as below:
  1. <div id="test"></div>
    <asp:TextBox ID="txtRDate" runat="server" Width="120px" ClientIDMode="Static"  AutoPostBack="True" OnTextChanged="txtRDate_Te
    xtChanged">
    </asp:TextBox>

Javascript code is:

  1. <script type="text/javascript">
    $('#test').datepicker({
        dateFormat: 'yy/mm/dd',
        minDate: new Date(2017, 1, 1),
        defaultDate: new Date(),

    onSelect: function(date, obj){
        $('#txtRDate').val(date);  //Updates value of date
     $('#txtRDate').trigger('ch
    ange');
    }
    });
    </script>

when select date from datepicker the TextChanged for textbox fired and do postback.

c# Code behind:
  1. protected void txtRDate_TextChanged(objec
    t sender, EventArgs e)
      {
            GetData(txtRDate.Text);
      }

Kindly advise me how  to keep datepicker with date value selected after auto postback event?
