              ->add('save','submit') 
    ;
}

Try something like this

{{ form_widget(form.form.dateDeLaDemande, {value : currentDate}) }}

To declare a variable in twig :

{% set currentDate = "now"|date("m/d/Y")  %}

or directely :

 {{ form_widget(form.form.dateDeLaDemande, {value : "now"|date("m/d/Y")}) }}
