Hi amar__,
It seems you're having trouble with a third party widget and we can help.
Make sure you have Background App Refresh enabled for the app that's providing the widgets:
Use Background App Refresh
After you switch to a different app, some apps run for a short period of time before they're set to a suspended state. Apps that are in a suspended state aren’t actively in use, open, or taking up system resources. With Background App Refresh, suspended apps can check for updates and new content.
If you want suspended apps to check for new content, go to Settings > General > Background App Refresh and turn on Background App Refresh. If you quit an app from the app switcher, it might not be able to run or check for new content before you open it again.

Switch apps on your iPhone, iPad, or iPod touch
If background app refresh is on for the app and it's still not updating, contact the app developer for guidance:
