Based on above, looks you are struggling to have a handle on dropdown inside Grid via jQuery/JavaScript.
For ASP.NET, you would have something like:

ASP.NET

<asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
    <ItemTemplate>
        <%# Eval("Country") %>
    </ItemTemplate>
    <EditItemTemplate>
        <asp:DropDownList ID="ddlCountries" runat="server">
            <asp:ListItem Text="Please select" Value="" />
            <asp:ListItem Text="United States" Value="United States" />
            <asp:ListItem Text="India" Value="India" />
            <asp:ListItem Text="France" Value="France" />
            <asp:ListItem Text="Russia" Value="Russia" />
        </asp:DropDownList>
    </EditItemTemplate>
</asp:TemplateField>
