It is quite unusal that a decoder would need parameters in order to
work. As you have not told us what kidn of reconfiguration you need to
do we can't suggest you potetially easier ways to achive what you want.
With the information you gave, you will need to listen to element-added
signals on each bin recursively until you have your element.
