withSelect Option under DTOptionBuilder not working

I am struggling in implementing the code used in the following code.

http://l-lin.github.io/angular-datatables/archives/#!/withSelect

when I try to include following piece of code under my DTOptionBuilder I am getting an error **withSelect ** property saying that it is not an Option

.withSelect({
            style:    'os',
            selector: 'td:first-child'
        });

What I am trying to achieve is an angular datatable with checkboxes which enables user to select single or multiple rows by checking checkboxes
There is precursor tho this question which led me to ask this question. Please take a look at the following link
