I have a hierarchical grid using a template, but I'm unable to figure out the correct way to use a custom filter in the template.

I wrote about it on StackOverflow yesterday, but it won't hurt trying the forums either.

I don't mind throwing the code around.

The structure of the data I use is this: 

[
{
"date": "${Y.m}",
"new": "${new}",
"active": "${active}",
"inactive": "${inactive}",
"clients": [
{
"client_id": "${client_id}"
"administration_name": "${name_of_administration}",
"created_at": "${created_at}",
"updated_at": "${updated_at}",
"is_new": "${new}",
"status": "${status_id}"
}
]
}
}
]

Better formatting, somehow the forum doesn't like using tabs, and no edit button. 

[
    {
        "date": "${Y/m}",
        "new": "${new}",
        "active": "${active}",
        "inactive": "${inactive}",
        "clients": [
            {
                "client_id": "${client_id}"
                "administration_name": "${name_of_administration}",
                "created_at": "${created_at}",
                "updated_at": "${updated_at}",
                "is_new": "${new}",
                "status": "${status_id}"
            }
        ]
        }
    }
]

Has been fixed, thanks to this SO user.
Instead of detailInit, you're supposed to use dataBound, which works perfect.
