Joel Pou gave here  a correct answer, and link to a project for downloading:

But now, I can't download the file, because it is removed.  I have tried to duplicate the project, but it won't work......

Anoyone who knows how to do this?   Here is what I get:

var sporsmal=sym.$("sporsmal");

sporsmal.html('<form><input type="radio" name="spm1" value="right" />London</br>'

+'<input type="radio" name="spm1" value="wrong"/>Hamburg'

+'</form');

sym.$("sporsmal").change(function()

   {

     if sym.$("sporsmal").value==right then

     alert ('you ae right');

   }

);

The change part works fine, if I replace the if tewst with a alert, I get an alert  but I'm not able to get the value
