`this` bound to window? - Expose Input field to the API.

I am really struggling with trying to grab a reference to the input field. Internally there seems to be a `this.$input` that should relate the the current input field. However, this isn't accessible through the API (to my knowledge) and all references to `this` return the `window` object.

The problem I am finding is due to the fact that I'm binding to multiple inputs, this is clearly not the default behaviour that the twitter devs intended, but I believe it makes sense.

```
var data = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace("name"),
queryTokenizer: Bloodhound.tokenizers.whitespace,
identify: function(obj) { return obj.objectId; },
remote: {
url: '/team/management/suggest',
prepare: function(query, request){
console.log(this); // Bloodhound object
var name = $(":focus").attr("name");
request.url = request.url + '?'+ name +'=' + query;
return request;
}
}
});

$('[role="typeahead"]').typeahead({
minLength: 2,
highlight: true,
classNames: {
wrapper: "suggestion-wrapper"
}
}, {
name: 'players',
display: 'name',
source: data,
limit: 100,
templates: {
suggestion: function(obj){
console.log($(this)); // Window object
var name = $(":focus").attr("name");
if(name == "form_team_manage_ground"){
return '

';
}

return '

';
},
notFound: function(obj){
console.log(this); // Window object
var name = $(":focus").attr("name");
if(name == "form_team_manage_ground"){
return ''
}

return '

';
}
}
})
```

This was working well, until the latest release of Safari, it seems that `:focus` doesn't populate until after the suggestion engine kicks in, this means that I get `undefined`.

I would like for the input field to be exposed so that we don't need to rely on `:focus`.

Can somebody point me in the right direction as this library's source seems highly complex?

Cheers.
