Try with data attribute, it will help u.

function renderEqdam(element) {
    var $ele = $(element);
    $ele.empty();
    $ele.append($('<option />').val('0').text('Select'));
    $.each(Eqdams, function (i, val) {
        $ele.append($('<option/>').val(val.EqdamName).text(val.EqdamName).attr('data-EqdamPrice', val.EqdamPrice ).attr('data-id', val.id));
    })
}

$('#foo').on("change",function(){
    var dataid = $("#foo option:selected").attr('data-EqdamPrice');
    alert(dataid)
});
