在选择中附加选项

What is wrong with this part of js code ?

I want to append some data in my select.

$.each(data.souscommande, function (index, value) {
    $('#cfrnscmdid').append($('<option/>', {
        value: value.producteurid,
        text: value.producteurnom
    }).prop('selected', data.scmdtrp == value.nom));
});

I want to delete the function selected but if i do i will have a problem with }); .

 $('#cfrnscmdid').append($('<option>', {
     value: data.id
 }).text(data.nom));
