bootstrap checkbox alignment?

hi,
My site is bootstrapped and in a form layout I have a single check box
the problem is that it appears on line below the text and I want it to stay on same line
here is my code
        <div class="form-group">       <label for="pwd">Tick box if you like to come <span> <asp:CheckBox ID="CheckBox1" class="radio" runat="server" onchange="javascript:ShowPanel1()" />   </span> </label>                    </div>


thank you
