JavaFX, erros de compilação urgente!

Olá pessoal, preciso de uma ajuda urgente, estou fazendo um curso de JavaFX, e nele temos que fazer uma calculadora utilizando o Scene Builder, consegui fazer tudo que foi pedido, porem quando vou colocar no onAction, ao gerar o método de de execução do botão, no XML ele aparece com um “#”, exemplo: onAction="#onClickNumeros", e acredito que por esse motivo o Netbeans não está compilando o código, e nem encontrando o método no arquivo de controle.

Nas linhas em que tem o “#” aparece a seguinte mensagem: “O controlador não é definido no componente raiz”, já estou a três dias pesquisando para resolver isso, preciso muito de ajuda com isso para poder evoluir no curso

Agradeço de mais se alguém conseguir me ajuda!!
