Is it possible to push an empty child info table to a field in parent info table?

I'm trying to push an empty child infotable to a field (of basetype : infotable) in parent infotable

var InvalidAssets = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape({
infoTableName: "InfoTable",
dataShapeName: "ChildInfotable.DS"
});
var output = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape({
infoTableName: "InfoTable",
dataShapeName: "ParentInfotable.DS"
});
var message = "Please enter name";

output.AddRow({
"InvalidAssets" : InvalidAssets, //infotable
"StatusMessage" : message //string

});
var result = output;

attached is the output I'm seeing... but I would like to have empty infotable in the "InvalidAssets" feild as I'm trying to bind the child infotable from the output of the service to a grid in mashup.
