.Net produces span tag for CSS for Radiobutton controls

Hi,

I am working on ASP.net2.0 website using C#

I have a .net radiobutton control as follows:


<asp:RadioButton ID="RadioButton1" class="js-required" data-validate="isFilled" runat="server" />

When it renders it produces the result

        <span class="js-required" data-validate="isFilled"><input id="RadioButton1" type="radio" name="RadioButton1" value="RadioButton1" /></span>

After rendering can .Net produces the result as follows:

<input id="RadioButton1" type="radio" name="RadioButton1" value="RadioButton1" class="js-required" data-validate="isFilled"/>

I mean I donot wanted <span class="js-required" data-validate="isFilled"> around input control

As it is giving hard time in jquery to understand radiobutton class

Please suggest

Thanks
