I tried this example below and it is working with the latest jquery version.

    <script type="text/javascript">
    $(document).ready(function () {
        $("#chk").change(function () {
            var $this = $(this);
            var checked = $this.is(':checked');
            if (checked) {
                alert('checked');
            }
        });
    });
</script>
<input id="chk" type="checkbox" />

$(function(){
    $('#selectAll').change(function(){ 
        alert("value changed");
    });
});

See a working demo.

$('#selectAll').bind('change',function(){ 
    alert("hi");
});

Use 'change' instead! jsFiddle
