How to handle Form's onSubmit function in nativebase?

Question

I want to use redux-form in nativebase but it does not work quite as same as using in web. I don't think my onSubmit callback is not getting invoked and I am not sure why.

import React, { Component } from 'react';
import { reduxForm, Field } from 'redux-form';
import {
  Container,
  Content,
  Item,
  Input,
  Button,
  Form,
  Label,
  Text,
  Icon
} from 'native-base';

import * as actions from '../actions';

class Signin extends Component {
  handleFormSubmit({ username, password }) {
    this.props.userSignIn({ username, password });
  }

  renderUsername() {
    return (
      <Item floatingLabel>
        <Icon name="ios-person" />
        <Label>Username</Label>
        <Input autoCorrect={false} autoCapitalize="none"/>
      </Item>
    );
  }

  renderPassword() {
    return (
      <Item floatingLabel>
        <Icon name="ios-lock" />
        <Label>Password</Label>
        <Input secureTextEntry={true} />
      </Item>
    );
  }

  renderLoginBtn() {
    return (
      <Container style={styles.button}>
        <Content>
          <Button primary action="submit">
            <Text>Login</Text>
          </Button>
        </Content>
      </Container>
    );
  }

  render() {
    const { handleSubmit, fields: { username, password } } = this.props;
    return (
      <Container style={styles.container}>
        <Content>
          <Form onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>
            <Field name="username" component={this.renderUsername} />
            <Field name="password" component={this.renderPassword} />
            {this.renderLoginBtn()}
          </Form>
        </Content>
      </Container>
    );
  }
}

function mapStateToProps(state) {
  return {
    errorMsg: state.auth.error
  };
}

export default reduxForm({form: 'signin', fields: ['username', 'password']}, mapStateToProps, actions)(Signin);

I cannot find anywhere else how to use onSubmit callback with nativebase Form.

If you look at native base documentation its says.

"Note: Form in native base is just a wrapper around the inputs and hence has no onSubmit function"

You should define you own button or touchablehighlight and use onPress callback
