Calendar always visible

This is my CSS
```

```

This es my JS
```

```
In a sigle js:
```
$('#date').pickadate({
monthsFull: ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'],
monthsShort: ['Ene', 'Feb', 'Mar', 'Abr', 'May', 'Jun', 'Jul', 'Ago', 'Sep', 'Oct', 'Nov', 'Dic'],
weekdaysFull: ['Domingo', 'Lunes', 'Martes', 'Miercoles', 'Jueves', 'Vieres', 'Sabado'],
weekdaysShort: ['Dom', 'Lun', 'Mar', 'Mie', 'Jue', 'Vie', 'Sab'],
today: 'Hoy',
firstDay: 1,
clear: '',
close: 'Cerrar',
format: 'dd-mm-yyyy',
formatSubmit: 'dd-mm-yyyy',
closeOnSelect: false,
closeOnClear: false,
container : '#date_calendar_container'
});

```

My Laravel 5.2 HTML view
```

But in the browser appears:
I didn't understan why calendar it's always visible and without styles.
I read docs and check my code with the examples, but it's all correct
