NeoEloquent Class not found Symfony\Component\Debug\Exception\FatalThrowableError - php

Question

I'm trying to create a link in between 2 objects using NeoEloquent. Unfortunately i get the following error.
Class 'Permission' not found
I tried pretty much everything but i can't get it to work unfortunately.
I submit the permission objects I want to link to as an integer representing the id of the label.
The relationship between the labels is a Many to Many relation. As far as i can see i've done everything correctly. I've checked with the GitHub page, it looks good to me.
Thanks in advance!
Controller method:
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param Role $role
* #return \Illuminate\Http\Response
*/
public function update(Request $request, Role $role)
{
//dd($request);
$this->validate($request, [
'title' => 'required',
]);
foreach($request['permission'] as $perm){
$role->permissions()->attach($perm);
}
$role->title = request('title');
$role->save();
return redirect("/roles");
}
Role Model:
<?php
namespace App;
use Vinelab\NeoEloquent\Eloquent\Model as NeoEloquent;
class Role extends NeoEloquent
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'title',
];
protected $label = "Role";
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
];
public function permissions(){
return $this->hasMany('Permission', 'Has_Permission');
}
}
Permission Model:
<?php
namespace App;
use Vinelab\NeoEloquent\Eloquent\Model as NeoEloquent;
class Permission extends NeoEloquent
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'title',
];
protected $label = "Permission";
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
];
}
