BI to BA conversion not resolving nested nodes

While converting following data

ImmutableContainerNode{
nodeIdentifier=(urn:opendaylight:params:xml:ns:yang:hc:data?revision=2015-01-05)cont-under-list,
value= [
ImmutableContainerNode {
nodeIdentifier=(urn:opendaylight:params:xml:ns:yang:hc:data?revision=2015-01-05)cont-under-list,
value= [
ImmutableLeafNode {
nodeIdentifier=(urn:opendaylight:params:xml:ns:yang:hc:data?revision=2015-01-05)nested-name,
value=nestedName,
attributes= {

}
}
],
attributes= {

}
}
],
attributes= {

}
}

with following logic

@Nonnull
default Map.Entry<InstanceIdentifier<? extends DataObject>, DataObject> nodeBinding(
@Nonnull final BindingToNormalizedNodeCodec serializer,
@Nonnull final YangInstanceIdentifier identifier,
@Nonnull final NormalizedNode<?, ?> data) {
try {
return serializer.toBinding(new AbstractMap.SimpleImmutableEntry<>(identifier, data))
.or(() ->

{ throw new IllegalArgumentException( String.format("Unable to create node binding for %s|%s", identifier, data)); }

);
} catch (DeserializationException e)

{ throw new IllegalArgumentException(String.format("Unable to deserialize node %s|%s", identifier, data)); }

}

The resulting data looks like

InstanceIdentifier{
targetType=interface org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hc.data.rev150105.simple.container.simple.list.ContUnderList,
path= [
org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hc.data.rev150105.SimpleContainer,
org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hc.data.rev150105.simple.container.SimpleList [
key=SimpleListKey [
_name=nameUnderSimpleList
]
],
org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hc.data.rev150105.simple.container.simple.list.ContUnderList
]
}" -> "ContUnderList{ // here should be leaf as can be seen in BI data
augmentations= {

}
}"
