React native undefined 不是一个函数

Question

我是 React Native 的新手。我正在尝试推送到另一个页面。但我收到错误提示

Undefined is not a function(evaluating '_this2._goToProductListing('app.productListing'{title:item.title})')

我的代码是这样的

 _renderContent(section, i, isActive) {
        return (
            <View>
                <List>
                    {section.content.map((item, i) => {
                        return(
                            <ListItem containerStyle={styles.categoryLists}
                                      onPress={() => this._goToProductListing('app.productListing',{title:item.title})}
                                      key={i} title={item.title}
                            />
                        );
                    })}
                </List>
            </View>
        );
    }


    //Send to product list page
    _goToProductListing = (screen,data) => {
        this.props.navigator.push({
            screen: screen,
            title: data.title,
            passProps: {
                data: data
            }
        });
    };
render() {
        return (


            <View style={stylesheet.accrodianWraper}>

                <ScrollView>
                    <Accordion
                        activeSection={this.state.activeSection}
                        sections={CONTENT}
                        touchableComponent={TouchableOpacity}
                        renderHeader={this._renderHeader}
                        renderContent={this._renderContent}
                        duration={0}
                        onChange={this._setSection.bind(this)}
                    />
                </ScrollView>
            </View>
        )
    }

谁能告诉我哪里做错了？？我该如何解决？

导航我使用wix react native navigation，页面app.productListing也在index.js中注册。我正在为手风琴使用 react-native-collapsible， B

尝试使 _renderContent 也成为带有箭头函数的属性：

_renderContent = (section, i, isActive) => {
