Banners not recognized by certain commands

So I am trying to make a mini game. I need this command:

execute @a[team=Red] ~ ~ ~ detect ~ ~ ~ banner 4 /replaceitem entity @p[team=Red,c=1] slot.armor.head banner 1 4

When I run this command in a command block it says in the output box:

There is no such item with name minecraft:banner

It works works with the /give command like:

/give

{Insert name here}

banner
