Dynamic loop creation DOM，passing a callback function as a component property，cannot be obtained in the component

[no5no6]

I packaged a component, import the component,dynamic loop creation DOM , Passing a callback function as the component property，In packaged component, the property is undefined，I use the method is wrong？

in AnimateImage.js
This line of code is wrong

// print undefined, If don't create DOM dynamically, this property can be obtained.
console.log(onPress, 'onPress');  

Game.js

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  TouchableWithoutFeedback,
  Text,
  View

} from 'react-native';

import AnimateImage from '../control/AnimateImage';
import _ from 'lodash';

export default class Game extends Component {
  constructor(props){
    super(props);
    let {imageArray} = this.props;
    this.state = {
      rows: [],
      imageArray: imageArray || [],
    };
  };

  componentDidMount(){
    this.createPokers();
  };

  onPress = () => {
    console.log('sucess');
  }

  //imageArray = [1,2,3,4]
  createPokers = () => {
    let self = this;
    let rows = imageArray.reduce(function(memo, value){
      memo.push(
          <AnimateImage
            key={'backImage'+ value}
            style={{left: 0 - value * 120}}
            animate="bounceInLeft"
            imageHeight={220}
            imageWidth={150}>
            onPress={self.onPress}
          </AnimateImage>
      );
      return memo;
    }, []);
    this.setState({rows: rows});
  };


  render() {
    return (
      <View>
        <View ref="viewPoker" style={[styles.viewRow, styles.AnimateImage]}>
          {this.state.rows}
        </View>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  viewRow: {
    flexDirection: 'row',
    position: 'absolute',
  },
  AnimateImage: {
    left: 150,
    top:300,
  }
});

AppRegistry.registerComponent('Game', () => Game);

AnimateImage.js

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Image,
  TouchableWithoutFeedback,
  Text,
  View
} from 'react-native';

import * as Animatable from 'react-native-animatable';

export default class AnimateImage extends Component {
  constructor(props){
    super(props);
    let {animate, text, imageHeight, imageWidth, style, onPress} = this.props;
    console.log(onPress, 'onPress');  // print undefined
    this.state = {
      animate: animate || '',
      imageHeight: imageHeight || 300,
      imageWidth: imageWidth || 200,
      style: style || {},
      callback: onPress || {}
    };
  };

  buttonPress = () => {
    this.refs.view.fadeOutUpBig(1500).then((endState) => {
      this.state.callback();  
    });
  };

  render() {
    return (
      <TouchableWithoutFeedback onPress={this.buttonPress}>
        <Animatable.View animation={this.state.animate} ref="view">
          <Image
            style={[this.state.style, {height: parseInt(this.state.imageHeight), width:parseInt(this.state.imageWidth)}]}
            source={require('./../../src/images/poker-back.png')}
          />
        </Animatable.View>
      </TouchableWithoutFeedback>
    );
  }
}



AppRegistry.registerComponent('AnimateImage', () => AnimateImage);
