回声框架Bind（）html FormData

Question

I have a Form html like :

<input name="email"type="email" />
<input name="password"type="password" />
<input name="tags[name][]"type="text" />
<input name="tags[count][]"type="number" />
<input name="tags[name][]"type="text" />
<input name="tags[count][]"type="number" />
<input name="tags[name][]"type="text" />
<input name="tags[count][]"type="number" />
<input name="freeword[]"type="text" />
<input name="freeword[]"type="text" />

I want to Bind() this form with my struct like :

type UserFrom struct {
  Email string `json:"email" form:"email" query:"email"`
  Password string `json:"password" form:"password" query:"password"`
  Tags []Tag
  Free []string `json:"freeword[]" form:"freeword[]" query:"freeword[]"`
}
type Tag struct {
  Name string `json:"tags[name][]" form:"tags[name][]" query:"tags[name][]"`
  Count string `json:"tags[count][]" form:"tags[count][]" query:"tags[count][]"`
}

But if i print the result of Bind() after POST i have :

u := new(UserFrom)
if err = c.Bind(u); err != nil {
  return
}
log.Println(u)

This bad Output :

&{[e-mail] pwdpwdpwd [] [word1 word2]}

The row Tags []Tag in UserFrom struct does not work

If y try to change Tags []Tag to Tags Tag i have a good last entry

&{[e-mail] pwdpwdpwd {tag3 3} [word1 word2]}

I want this output :

&{[e-mail] pwdpwdpwd [{tag1 1} {tag2 2} {tag3 3}] [word1 word2]}

do you have an idea of the problem ?

Thx @alexaandru for your reply,

I have update form fields to :

<input name="tags[][name]"type="text" />
<input name="tags[][count]"type="number" />
<input name="tags[][name]"type="text" />
<input name="tags[][count]"type="number" />
<input name="tags[][name]"type="text" />
<input name="tags[][count]"type="number" />

And i have create a simple for

u := new(UserForm)
if err := c.Bind(u); err != nil {

}

fiels, _ := c.FormParams()
var tags []Tag
var tag Tag
for i := 0; i < len(fiels["tags[]tag"]); i++ {
    count, _ := strconv.Atoi(fiels["tags[][count]"][i])

    tag.Name = fiels["tags[][name]"][i]
    tag.Comment = count

    tags = append(tags, tag)

}

u.Tags = tags
log.Println(u)

I have nice output :

&{[e-mail] pwdpwdpwd [{tagX 1} {tagY 2} {tagZ 3}] [wordX wordY]}
