Firing two functions from an event listener (one throttled, the other not)

I have an event listener for scroll events that fires a function responsible for appending an element to the viewport. That same scroll event listener is being throttled to prevent a downpour of scroll events (more manageable). The library being used to throttle is throttle-debounce. Problem: throttling handlePageScroll is throttling everything contained in that method (of course).

Code:

componentDidMount() {
  window.addEventListener('scroll', throttle(2000, this.handlePageScroll));
}

handlePageScroll = () => {
  someFn() // logic for appending an element, does not need throttling
  this.loadNextBatch(); // logic that actually needs to be throttled
};

I’ve tried throttling from within handlePageScroll with no success. Is there way to fire two functions from an event listener?
Thank you in advance.
