I have a following function in TS, that creates a custom element on the fly.

export function element(name: string, extension?: string) 
return function<TFunction extends Function>(target: TFunction): TFunction 
 const descriptorMap = getPropertyNames(target).reduce(
 (acc: PropertyDescriptorMap, k: string) => 
 acc[k] = getPropertyDescriptor(target, k);
 return acc;
 , <PropertyDescriptorMap>);


 if (!descriptorMap["createdCallback"]) 
 descriptorMap["createdCallback"] = 
 value: function() 
 target.call(this);
 
 ;
 
 const base = extension ?
 Object.getPrototypeOf(document.createElement(extension)) :
 HTMLElement.prototype;
 const proto = Object.create(base, descriptorMap);

 let ctor = document.registerElement<TFunction>(name, extension ? 
 prototype: proto,
 extends: extension
 : 
 prototype: proto
 );

 (<any> ctor).tagName = name;
 (<any> ctor).extends = extension;
 return ctor;
; 

I'm trying to change the registerElement logic to use customElements.define, but with no luck. Is there anyone who can help me with this? Thanks
