Force data.getItemMetaData

[Kathryn Simmons]

I have setup a way to highlight my rows as necessary in the following call:

dataB = @Html.Raw(Json.Encode(Model.selectedFields));

dataB.getItemMetadata = function(row) {

            var dLength = Object.keys(dataB).length - 1;

            var item = "";

            if (row < dLength)

                item = dataB[row]["Filter"];

            if (item != "" && item != undefined) {

                return { cssClasses: 'highlight' }

            } else {

                return {}

            }

        }

This works until I make a row change (i.e. remove a row or reorder my rows).  How can I force this to be called again?  I tried invalidating the grid, but that didn't work.
