It might help you.

This example basically used for filter observable array by passing input parameters at the key up event.

This function works (based on http://knockoutjs.com/examples/animatedTransitions.html :)

get: function(role) 
{
    return ko.dependentObservable(function () 
    {
        return ko.utils.arrayFilter(this.personRoles(), function(item) 
        {
            return item.id == role;
        });                


    }, viewModel); 
}
