Javascript

I have a radio button , from which i pass the value to db , and in another page i fetch the data and display the form back , when the radio button is checked , its getting unchecked on second click, how do i get to uncheck on first click itself?

What I have tried:

<a id="element1" onClick="javascript:changeText(0);docheck(this);">Mark</a>
<input type="radio" id="element11" onClick="javascript:changeText11(1);docheck11(this);" name="test11" checked="checked"><br />
<script>

function changeText11(idElement) {
    var element = document.getElementById('element' + idElement);
    if (idElement === 1 || idElement === 2) {
        if (element.innerHTML === 'Mark') element.innerHTML = 'Unmark';
        else {
            element.innerHTML = 'Mark';
        }
    }
}

var check;

$('input[type="radio"]').hover(function() {
    check = $(this).is(':checked');
});

$('input[type="radio"]').click(function() {
    check = !check;
    $(this).attr("checked", check);
});

var checkedradio;
function docheck11(thisradio) {
    if (checkedradio == thisradio) {
        thisradio.checked = false;
        checkedradio = null;
    }
    else {checkedradio = thisradio;}
}

</script>
