Find and FindChild methods returning functions instead of objects

Working with a dev and unable to see why this keeps happening. We narrowed it down to the find method using the following:

this.GetComboBoxItemByText = function (text) {
        var thing = this.Popups.GetPopupByIndex(1)
            .WPFObject("PopupRoot", "", 1)
            .WPFObject("Decorator", "", 1)
            .WPFObject("NonLogicalAdornerDecorator", "*", 1);
        var thing2 = thing.FindChild("TextBlock", text, 2, true);
        return thing2;
    }

When looking at the local variables,

thing is an object

thing2 is a function

thing2 should be an object, and is failing when trying to click on it after this call.
