Add new lines using vertical VIM selection

Question

Assume the following file contents are opened in VIM:

function a1 {}
function a2 {}
function a3 {}
function a4 {}
function a5 {}
function a6 {}
function a7 {}

I want to expand all the functions in this style:

function an {

}

For this, I tried using vertical selection (using Ctrl+ V):

function a1 {█
function a2 {█
function a3 {█
function a4 {█
function a5 {█
function a6 {█
function a7 {█

Then I clicked I. Then Enter(in insert mode):

function a1 {
}
function a2 {}
function a3 {}
function a4 {}
function a5 {}
function a6 {}
function a7 {}

Then I clicked Esc. I expected to expand all the blocks. Nothing happened. Why?

I know that a simple replacement or macro will save me. I know there are alternatives, but I want to know why a new row was not added when using vertical selection.

read at the bottom of your answer and realized that you weren’t looking for a workaround ... I'm not sure why it doesn’t work.
