need to pass fields into generic Modal popup onClick on a button in inner field

[srivshreya]

http://angular-formly.com/#/example/advanced/repeating-section

In this example , in the inner fields, I have a button as a field and I want to open a modal popup on the click of that button. and I need to pass all the fields with their model values. So that i can edit that particular investment. Currently I am able to pass only model. I want to make my modal popup more generic and so I want it to take fields as well from the JSON.

Hoping you could guide me on the same.
