jQuery document.ready event binds Click event when the Page Loads but when AJAX UpdatePanel does PostBack the attached clicked events are removed and hence the Click event does not work.

Here Mudassar Ahmed Khan has explained how to solve the issue of jQuery Click event handler not working after Partial PostBack of AJAX UpdatePanel in ASP.Net.

BackHandler The Backhandler API detects hardware button presses for back navigation, lets you register event listeners for the system's back action, and lets you control how your application responds.

The ngClick directive allows you to specify custom behavior when an element is clicked. We should also remove the listener when we are jumping out from the screen (where we have added the listener) because sometimes after going to the next screen or any other screen the listener remains active in the background if the last screen is in the stack and not killed by the system.

To handle the Android Back Button Press in the React Native we have to register the hardwareBackPress event listener with a callback function, which will be called after pressing the Back Button.

If jQuery is making DOM changes that React doesn’t know about, some node that gets reused might be in an unexpected state. Some of React’s efficiency comes from reusing DOM nodes on the page when things change, rather than always inserting or deleting nodes. React will have no idea about the changes that jQuery has made.
