How to extend angular @input decorator?

Question

I'm trying to write custom property decorator for extending skills of angular @Input decorator.

My goal is to get Localizable property with existing property selector.

./decorators/my-decorators.ts

import {Input} from '@angular/core';
export interface InputDefinition {localizable: boolean; selector: string; }
export function MyInput(inputDefinition: InputDefinition) {
    const ngInput = Input(inputDefinition.selector);
    return function (target: any, key: string) {
        if (inputDefinition.localizable === true) {
            console.log(`loclizable input ${inputDefinition.selector}`);
            // implement localization for property.
        }
      ngInput(target, key);
    };
}

./my-component/mycomponent.ts

import { Component, Input } from '@angular/core';
import { MyInput } from '../decorators/my-decorators';

@Component({
  selector: 'my-component',
  template: `<h1>{{myInput}}</h1>`
})
export class MyComponent {
  //define input property with custom decorator 
  @MyInput({selector: 'my-input', localizable: false})
  myInput = 'input default value';
}

./app.component.html

<div style="text-align:center">
  <my-component my-input="bound value"></my-component>
</div>

ng serve

seems to work great but when I run it in prod mode..

--ng serve --prod

has no any build error or runtime error but property binding not working in prod build.

All kinds of suggestions will help.

thanks in advance
