i am using  "react-native-router-flux": "^3.38.0". I need to call the componentWillMount of a page, but after the first time that it gets there the componentWillMount does not get called.
Edition:
please below find the code for navigation:
const RouterComponent = () => {
  return (
    <Router sceneStyle={{ paddingTop: 65 }} navigationBarStyle={{ backgroundColor: '#81b71a' }}>
      <Scene key='auth' initial>
        <Scene key='login' component={LoginForm} title='login here' />
      </Scene>
      <Scene key='main' >
        <Scene key='employeeCreate' component={EmployeeCreate} title='create employee' />
        <Scene
        initial
          key='employeeList'
          component={EmployeeList}
          title='Emplyees'
          rightTitle='add'
          onRight={() => Actions.employeeCreate()}
        />
        <Scene
          key='employeeEdit'
          component={EmployeeEdit}
          title='edit employee'
        />
      </Scene>
    </Router>
  );
};
export default RouterComponent;
				
                        
It was a known issue in v3.38 which was fixed in a later version. Try updating the package to the latest version. Issue
4.0.0-beta.21 is the latest
