Laravel Eloquent (A Model attribute won't show) - laravel

Question

I have a Stat Class :
class Stat extends Model
{
public static function getByKey($key)
{
return Stat::where("key", "=", $key)->first();
}
public function getDates()
{
return json_decode($this->content);
}
}
In my database the Table stats contains only two columns (key, content)
When I execute this function in my view an error occurs
{!! \App\Stat::getByKey("ORDERS-DATA")->getDates() !!}
and this makes this error :
Exception message: Undefined property: App\Stat::$content
So I added these two lines to the getDates() to debug the error :
public function getDates()
{
dd($this->content);//This shows the same error
dd($this->attributes["content"]);//This works fine and show me what I want
return json_decode($this->content);
}
then I executed dd($this) and it shows this :
Stat {#486
#connection: "mysql"
#table: "stats"
#primaryKey: "id"
#keyType: "int"

#with: []

"updated_at" => "2019-04-01 14:11:02"
]

#guarded: array:1 [

}
And What I want is to get my content by $this->content, and I don't understand why it doesn't works ??
Please Help

The error is occurring because I have overrided one of the Laravel functions.
the name getDates OR getByKey OR getCounts is used by Laravel.
This is so weird this error happened to me two times in the same
day, Today's morning I created a function called getAttributes() and
showed me a total diferrent error. Why the community don't create a
list of functions names that we are not allowed to use, or use more
unique names ???
