Issues with parent change

We are working on a standard org chart (tree view) with the drag and drop feature to change hierarchy. This particular setup has a tool tip which displays details of the parent.
However the data in tool tip doesn’t refresh when the parent is changed. Could you please tell what might be the problem and how to solve it?
We are storing the chart data in a custom data object.

That would depend on how you implemented the tooltip, I think.
Tooltips aren’t something that GoXam provides.

I would guess that the data-binding isn’t defined right, but I really have no idea.
