How to access the value of an input disabled? : <p>I'm creating a reactive form in angular 2 and using material angular 2 to inputs;</p>

<p>I need to set an input as disabled and when submitting the value that is in the unlocked input the value to be sent. I Already created the input and the disabled is running. My problem is that when I give a submit value it does not come.</p>

<p>My code</p>

<pre><code>this.formVariacao = this._fb.group({

   id:[p &amp;&amp; p['id']],
   codigoItem: [p &amp;&amp; p['codigoItem'], Validators.required],
});
</code></pre>

<p>My html</p>

<pre><code>&lt;md-input-container&gt;
    &lt;input mdInput placeholder="Código da Variação" formControlName="codigoItem" name="codigoItem"&gt;
&lt;/md-input-container&gt;
</code></pre>

<p>I block the input as follows</p>

<pre><code>this.formVariacao.get('codigoItem').disable();
</code></pre>

<p>Only when I send the form the value does not come. Alguém pode me ajudar?</p>
