I don't know if this is an issue with React or IE11 but when an the input initially contains an EN-dash (8211) it fires the change event. 
JSFiddle http://jsfiddle.net/uH539/10/

nextProps = ReactDOMInput.getNativeProps(this, nextProps);
        break;
      case 'option':
        lastProps = ReactDOMOption.getNativeProps(this, lastProps);
        nextProps = ReactDOMOption.getNativeProps(this, nextProps);
        break;
      case 'select':
        lastProps = ReactDOMSelect.getNativeProps(this, lastProps);
        nextProps = ReactDOMSelect.getNativeProps(this, nextProps);
        break;
      case 'textarea':
        ReactDOMTextarea.updateWrapper(this);
        lastProps = ReactDOMTextarea.getNativeProps(this, lastProps);
        nextProps = ReactDOMTextarea.getNativeProps(this, nextProps);
        break;
    }
    assertValidProps(this, nextProps);
    this._updateDOMProperties(lastProps, nextProps, transaction);
    this._updateDOMChildren(
      lastProps,
      nextProps,
      transaction,
      context
    );
    if (this._tag === 'select') {
      
      
      transaction.getReactMountReady().enqueue(postUpdateSelectWrapper, this);
    }
  },
