yangdump does not generate handlers

[Proklink]

Hello, i have yang file with something like this content

grouping  foo-grouping {

        container foo {
            container config {
                presence "Configure foo";
                
                uses foo-config;
            } // END of config-container definition.

            container state {
                config false;
            
                uses foo-config;
            } // END of state-container definition.

            container foo-ports {
            
                uses foo-ports-top;
            } // END of foo-ports-container definition.

            uses evc-top;
        } // END of bridge-container definition.
    } // END of bridge-grouping definition.

    augment /baz:bars/baz:bar {
        when " /baz:bars/baz:bar/baz:type = '2' ";

        uses foo-grouping;
    }

yangdump does not generate handlers (in .c files) for containers foo-ports-top, evc-top, foo-config
