Handle current content + allow to keep model clean

Hi,

I fixed a tiny bug that needed a timeout so that angular is executed before jQuery, and I added a way to keep a model with a clean value of the number.
I didn't know if changing the "repository" URL as mandatory for my local bower to work, please remove this particular change if you merge in order not to break your cool work :)

Because I'm using this version in my project and I believe bower needs the URL to pull the repo. Of course you will need to put your repo's URL back into place afterwards.
