Laravel Model Not Saving - mysql

Question

Model is saving but all is null values excepts dates
There is not thrown error.
$fillable are directly copied from the field at my migrations.
I cant find why is that it is saving null values on the database
Here is my Code
My Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Disbursement_Information extends Model
{
use SoftDeletes;
protected $table = 'disbursement';
protected $fillable = [
'cv_number',
'payee_id',
'amount',
'check_number',
'release_date',
'first_collection_date',
'last_collection_date',
'maturity_date'
];
protected $dates = [
'created_at',
'updated_at',
'deleted_at'
];
}
My Controller
public function postDisbursement(Request $request, $id){
$loans = new Disbursement_Information;
$input = $request->all();
$loans->save($input);
}
