 * DataProvider accepts `onReady` function, which will execute once the data is ready.
 * Another approach would have been to simply return the data from dataProvider and let the
 * component await for it and then execute the required logic. We are going for callback instead
 * of async-await since we have debounce function in dataProvider. Which will delay the execution
 * of api call on trailing end of debounce (lets call it a1) but will return with result of
 * previous call without waiting for a1. So in this case, we want to execute onReady, when trailing
 * end of debounce executes.
