Sequelize -Encrypted Password Update using bcyrpt

Question

I have a problem password update with Sequelize. The problem is when I try to update, the password that was previously encrypted by bcyrpt, loses the encryption. below the code where I try to do

hooks: {
  beforeCreate: async usuario => {
    const salt = await bcrypt.genSaltSync()
    usuario.senha = bcrypt.hashSync(usuario.senha, salt)
  },
  beforeUpdate:async usuario=>{
    if(usuario.senha){
      const salt = await bcrypt.genSaltSync()
      usuario.senha=bcrypt.hashSync(usuario.senha, salt)
    }
  }

The encryption on before client, is happening perfectly, but when updating the password it loses the encryption. I thank anyone who can help
