Custom attribute jquery Datatables

I need create a custom attribute for my datatables instance, and I need keep this value, ex:

When I create an instance:

$('#table').dataTable({
    //common attributes
    ajax: 'url.json',
    columns: [...],
    //custom attribute
    hasSomeValueHere: 'helloword'
});

and I would like to keep it on settings of datatable, so if I check it will be there:

$('#table').dataTable({
    //common attributes
    ...
    fnDrawCallback: function(oSettings){
        alert(oSettings.hasSomeValueHere); //helloword
    }
});

There any way to extends datatable this way? Thanks

You dont need to extend dataTables for that. oSettings has an object, oInit, that holds the entire initialisation object, i.e the dataTables options. Example :

$('#example').dataTable({
    hasSomeValueHere: 'helloworld',
    fnDrawCallback: function(oSettings){
        alert(oSettings.oInit.hasSomeValueHere); //helloworld
    }
});

This works in 1.10.x as well, using DataTable() 

$('#example').DataTable({
    hasSomeValueHere: 'helloworld',
    drawCallback: function(settings){
        alert(settings.oInit.hasSomeValueHere); //helloworld
    }
});
