Weekpicker using Angular Directives for Bootstrap

I'm using the datepicker from Angular directives for Bootstrap [1] and everything works perfectly great. However, I now need to change the datepicker into a weekpicker.

I found multiple examples of how to do this using the standard jqueryUI datepicker [2][3][4], but I'm unable to understand how I'd do this with Angular.

Any pointers would be helpful

[4] Can I highlight an entire week in the standard Jquery UI date picker?
