Actually your files+=( "$input" ) expression is adding elements to your array but you are not iterating it correctly.

Your last loop should be:

for f in "${files[@]}"; do
    echo "element is: $f"
done

Test (thanks to @fedorqui)

$ a+=(1)
$ a+=("hello")
$ a+=(3)
$ for i in "${a[@]}"; do echo "$i"; done
1
hello
3
