possible to active input.focus() on initialization? 

Hello, awesome plugin. Works great and is easy to make changes to. One thing I haven't been able to figure out is how to trigger the input.focus() when the plugin is initialized.

I call the plugin inside a $('.btn').on('click')  event and would like the input already focused and ready to type instead of having to click the .editable text to focus the input.

Is this possible?
