try to put alert('') and check whether your JS is really working or not..

XML

function filladult(nopersons)
    {

    alert("you are here :" + nopersons);
     document.getElementById(<%= txtadult.ClientID %>).value= nopersons;
    }

or

XML

function filladult(nopersons)
    {

    alert("you are here :" + nopersons);
     $("#txtadult").val()= nopersons;
    }

Make sure you have included the js.min to your page for "$".
