Communicate angular component with non angular component

Hi folks,
i have a mvc application, my page has a partial view on teh top of the page and a angular component in the bottom. When i make a date change in the partial view, i need to trigger a method in the angular component. We tried by adding a input in the angular component html and set the value from the partial view on date change. New value is setting in teh angular component but im not able to trigger the event change which happened programmatically. Or is there any way i can call method inside the angular component from a partial view? Thanking you in advance.
