[Custom Components] I need help in creating a custom component (button) which can trigger my angular source code functionality. Example: on the form renderer the custom button will trigger a local angular code function which will open a custom modal pop-up i want to fill the data from that form and populate that data into rendered formio form.

Have you tried configuring a button with a custom event? See here: https://help.form.io/userguide/form-building/form-components#button (see the "Event" param)
