private$session_bindings
Call a destroy
method to remove observer
and input
from obsolete session which happens
when filter_panel_srv
is called again in new FilteredData
object.
Inputs are not stored directly in a field as they don't have destroy
method. Instead, we
store callback destroy
function for inputs which removes bindings from a session
.
