点击无法绑定renderjs内的函数，提示module not defined

H5端正常，App端真机调试时无法正常使用

renderjs部分

<script module="testModule" lang="renderjs">  
export default {  
    mounted() {  

    },  
    methods: {  
        sayHello(){  
            console.log("Say Hello!");  
        }  
    }  
};  
</script>

vue组件

<uni-button @click="consoleLog('666666');testModule.sayHello()">888</uni-button>

<script>  
    export default {  
        name: "FunctionPlotter",  
        data() {  
            return {  
                valu: '',  
                valus: [],  
            }  
        },  
        methods: {  
            consoleLog(v) {  
                console.log(v);  
            },  
            closeDialog() {  
                this.valu = '';  
                this.$emit('closeDialog', true);  
            }  
        }  
    }  
</script>

报错输出:
[Vue warn]: Property or method "testModule" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.
