Add a child node to a node at the specified index. This implementation does the following:
- If the
parentparameter is null or undefined, inserts thechildparameter at the specified index in the collection specified bymodelparameter. - If the
parentparameter has achildrenfield or property, the method adds thechildparameter to it at theindexparameter location. In this case, themodelparameter is not required. - If the
parentparameter does not have achildrenfield or property, the method adds thechildrenproperty to theparent. The method then adds thechildparameter to the parent at theindexparameter location. In this case, themodelparameter is not required. - If the
indexvalue is greater than the collection length or number of children in the parent, adds the object as the last child.
