Importer API error

[atatchin]

The object that is passed into setRowsDirty should be of type GridRow, instead its the one imported from
file or json....This is causing the following error on the log as already mentioned in #5815

addObjects: function (a, c, d) {
if (a.api.rowEdit) {
var e = a.registerDataChangeCallback(function () {a.api.rowEdit.setRowsDirty(c), e() }, [b.dataChange.ROW]);
a.importer.$scope.$on("$destroy", e)
}
a.importer.$scope.$apply(a.options.importerDataAddCallback(a, c))
}
