Seems like I am not having the actual parentContent at the time of
generating the child-polymer-element. If I assign hardcoded values in ready
function for this.parentContent, it doesnt work as well. If I assign
hardcoded values in create function for this parent.Content, it works. So,
I am not not sure if this is something related to generating the child
polymer element before the values getting binded to parent.

Also, it works if testDataChild is a string and not an array

Hi, I believe you’re hitting the condition where arrays, because they are
objects, are shared between every instance of your element in singleton
fashion. To work around this you need to not define the array, which will
be populated by the attribute binding, in the prototype but instead create
them in a “created” call-back inside your element’s script.

The reason you’re seeing it work correctly with strings is because, unlike
arrays and objects as I said above, strings and numbers are not shared
between instances of your element but are unique to each instance.
