go - Golang templates (and passing funcs to template)

Question

I'm getting an error when I try and access a function I'm passing to my template:

Error: template: struct.tpl:3: function "makeGoName" not defined

Can anyone please let me know what I'm doing wrong?

Template file (struct.tpl):

type {{.data.tableName}} struct {
  {{range $key, $value := .data.tableData}}
  {{makeGoName $value.colName}} {{$value.colType}} `db:"{{makeDBName $value.dbColName}},json:"{{$value.dbColName}}"`
  {{end}}
}

Calling file:

type tplData struct {
    tableName string
    tableData interface{}
}

func doStuff() {
    t, err := template.ParseFiles("templates/struct.tpl")
    if err != nil {
        errorQuit(err)
    }

    t = t.Funcs(template.FuncMap{
        "makeGoName": makeGoName,
        "makeDBName": makeDBName,
    })

    data := tplData{
        tableName: tableName,
        tableData: tableInfo,
    }

    t.Execute(os.Stdout, data)
}

func makeGoName(name string) string {
    return name
}

func makeDBName(name string) string {
    return name
}

This is for a program that generates struct boilerplate code (in case anyone is wondering why I'm doing that in my template).
