HarmonyOS Native调用TS侧方法，会报错，TS侧方法也不能获取到对象的变量

// TS侧的方法定义，这里定义回调函数 call_back_function 并 声明一个方法 doTestMethod 
import napi from 'liblibrary.so'; 
export class QNtest { 
  private test: Number = 12 
  private call_back_function = (value: number) => { 
    console.log(`call_back: ${value}, QNtest.test: ${this.test}`) 
  }; 
  public doTestMethod(value: number) { 
    console.log(`doTestMethod: ${value}, QNtest.test: ${this.test}`) 
  } 
  constructor() { 
    console.log(`122313asfaf`); 
    napi.add(1, 2, this, this.call_back_function); 
  } 
}
