ngDialog modal closes on click

Question

I want to open a form in modal, where user can input few things and that stuff will be saved in backend. I came across this plunk which implements this thing.

But when i try to click anywhere to make an input, modal closes. I tried this in my local system as well - same behavior.

Tried following things but no result:

1. I used ngDialog.openConfirm but it doesn't allow me to click anywhere(only tabs work.)
2. Set closeByEscape to false - escape blocked but click makes modal disappear
3. Set closeByDocument to false - clicks disabled and only tab allowed

Basically i need a modal:

1. Which doesn't disappear on click and escape
2. Allows tabs and clicks to make input
3. Doesn't disappear on click in background
4. Calls some function when submit is clicked
5. Closes only when default close button is clicked
