extract element from object

[jjf...@gmail.com]

I'm not sure why this doesn't work...

    viewModel.getSister = ko.computed(function () {

        var sisID = this.selectedSister().SisterID;

        console.log("Result: ", sisID);

        return ko.utils.arrayFilter(viewModel.bioArray, function (item) {

            return item.SisterID == sis;

        });

    }, viewModel);

I've tried many variations of the above. 

SisterID is an element of the object as seen here: 

Result:

Object {SisterID: 1141, UsingName: "Mary", FamilyName: "Madeline", ReligiousName: "Mary", BaptismalName: "Mary Madeline"…}

if I do this:

    viewModel.getSister = ko.computed(function () {
        var sis = this.selectedSister();
        console.log("Result: ", sis);
        return ko.utils.arrayFilter(viewModel.bioArray, function (item) {
            return item.SisterID == sis.SisterID();
        });
    }, viewModel);

I just want to make sure that you figured out that the `sis` inside the top arrayFilter callback should be `sisID`.
