Jquery search working on my desktop device and also on chrome mobile emulator but not working in real device

I have a website which contains jquery search (search based on object properties) and the search result (HTML content) is appended from jquery. it is working perfectly fine on a web device and also on chrome mobile emulator (in dev console) but it is not working on the real device (Tested on both Android and IOS).

What might be the reason for that?
