有没有办法在d.ts文件中覆盖var声明？

initTaggingControls() {
    RTE.CanvasEvents.registerListener(RTE.CanvasEvents.editableRegionChangedEvent,     Function.createDelegate(null, this.onCustomTextChanged));
    RTE.CanvasEvents.registerListener(RTE.CanvasEvents.editableRegionBlurEvent,        Function.createDelegate(null, this.onCustomTextChanged));
    RTE.CanvasEvents.registerListener(RTE.CanvasEvents.editableRegionFocusEvent, Function.createDelegate(null, this.onCustomTextChanged));
}

RTE是SharePoint的一部分.Line declare var RTE: any;可以解决问题.问题在于Function.createDelegate因为我不能宣布或重新宣布它.

Functionvar已在lib.d.ts中声明.有没有办法覆盖var声明来添加自定义方法？

Function.createDelegate是Microsoft ajax Library的一部分.
