Radio button event are not correctly handled

[xavier335659]

Localstorage is updated only at first click on a radio button.

See jsfiddle :

Select one value, then select the second, and go back to the 1srt one. The localstorage will remain on the second value.

Problem is in persist function :
// some binded events are redundant (change & paste for example), persist only once by field val
if ( this.val === this.getVal() ) {
return;
}
The this.val is persisted on each input of the group.
Suggested fix :
// some binded events are redundant (change & paste for example), persist only once by field val
if (!this.$element.is('input[type=radio], input[type=checkbox]') && (this.val === this.getVal())) {
return;
}
