Missed a spot to pass in the index
updated min.js
Set finish button type to 'button' so that it doesn't cause a form submit.
Fixed issue 22. Multiple backdrops.
1. fixed issue #2: Dont always scroll to top, if the element is entirely visible, do not scroll to top.\n 2. show data can be gotten from ajax to keep HTML clean \n 3. added a few more options: nextButtonText for a simpler nextButton,prevButtonText,finishButtonText. Those attributes can also be overridded by a specific element's corresponding attribute such as data-bootstro-nextButtonText.\n 4. Added a few function handlers in option: onComplete,onExit.\n 5. options.margin added to keep element nicely visible within a some top margin
added bootstro.json for a sample ajax return from server
