Bug checking if there is a record if the button is disabled - LARAVEL

I'm having a bug it is not verifying correctly whether or not there is a related table record, it always comes from the current table and not from the other table

DATA YOU SHOULD CHECK IF YOU EXIST IN THE RENEWAL TABLE (nomerespo, nomealuno)

Ex: User requests a renewal and clicks on confirm ok, in case you want to return to the card he sees that the button has changed the name and is "subscribed" I did exactly that and I was not successful he brings the button with name inscribed without having done the registration before, follow the code below

- Model Registration

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Matricula extends Model
{
    protected $table = 'matricula';
    protected $fillable = ['user_id','nomealuno','nomedopai']; // user_id salva id do usuario quando cria uma matricula la tem um campo de email e nele eu posso visualizar no card renovação o nome do pai e do filhos cadastrados 


    public function user() {
        return $this->belongsTo('App\User');
    }   

    public function renovacao() {
        return $this->hasMany('App\Renovacao');

    }  
}

- Model Renovation

<?php
namespace App;

use Illuminate\Database\Eloquent\Model;

class Renovacao extends Model
{
    protected $table = 'renovacao';
    protected $fillable = ['nomerespo','nomealuno','status'];


    public function matricula() {
        return $this->belongsTo('App\Matricula');
    }
}

- Controller

public function listardados()
{ //Pega os registro cadastrado do usuario logado e joga no form 

    $matricula = Matricula::where('user_id', Auth::id())->get();

    //dd($matricula);
    return view('dashboard.renovacao.teste', compact( 'matricula'));
}

public function store(RenovacaoRequest $request){ // função salva no banco de dados 


    $user = Auth()->user();

    $dados = $request->get('rematricula');

    foreach ($dados as $key => $dado) {

        Renovacao::create($dado);
    }


    return view('dashboard.renovacao.confirmacao', compact ('renovacao'));
}

- Migration Enrollment

public function up()
{
    Schema::create('matricula', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->string('nomealuno');
        $table->string('nomedopai');
        $table->timestamps();

    });
}

- MIgration renewal

public function up()
{
    Schema::create('renovacao', function (Blueprint $table) {
        $table->increments('id');
        $table->string('nomerespo');
        $table->string('nomealuno');
        $table->string('status')->default('pendente');
        $table->timestamps();
    });
}

- FORM
