Custom Shiny Input Return List

Hi! I've made lots of custom shiny inputs but they've always returned a single value or a vector. I was wondering what the structure of my JS would need to be in order to return a list?

   ..... //shiny input binding
  getValue: function getValue(el) {
    var value = [
           {id :1, name:"a" },
           { id:2, name:"b"},
           { id:3, name"c"}
     ] 
     return value
  },

Desired Output

print(input$mything)

[[1]]
[[1]]$id
[1] 1

[[1]]$name
[1] "a"


[[2]]
[[2]]$id
[1] 2

[[2]]$name
[1] "b"


[[3]]
[[3]]$id
[1] 3

[[3]]$name
[1] "c"

What I'm getting right now:

  id name   id name   id name 
 "1"  "a"  "2"  "b"  "3"  "c"

Bonus question! Can I give this list attributes so I can return something else from JS back to r but my user doesn't have to see it? What would that look like?

   ..... //shiny input binding
  getValue: function getValue(el) {
    var attr = "test"
    var value = [
           {id :1, name:"a" },
           { id:2, name:"b"},
           { id:3, name"c"}
     ] 
     return value
  },

So input$mything would return the same thing or something similar to this?

dummy_input <- list(list(id = 1, name = "a"), 
             list(id = 2, name = "b"), 
             list(id = 3, name = "c")
             )
attr(dummy_input, 'custom_attr') <- "test"
