Manually close timepicker

Hi,

i can't close the timepicker as same way as datepicker :

for the datepicker that work perfectly
```
var picker = $('.pickadate').pickadate('picker');
picker.close();
```

but when i do the same with timepicker :
```
var picker = $('.timepicker').pickatime('picker');
picker.close();
```
there is an error

`Uncaught TypeError: picker.close is not a function(…)`

Do you have a solution ?

thank you in advance.
