Change events not working on browser - InfoPath Form

Problem
In infopath, you might face a problem that the change events for controls work on local system but when deployed to the server or run in browser, these change events might not work like change event for dropdown list, checked change event for Checkbox.

Solution
You just have to set an option in the properties of the control.
Right click on the control for which event is not working, click Control properties, probably the last option in the menu, and in the Properties windows, select "Browser forms" tab. You will find 3 options there,

1. Never
2. Always
3. Only when necessary for correct rendering of the form

By default, the 3rd option is selected, you have to select the 2nd option i.e "Always".
You problem is solved :)

Thanks for you time.
