Updated to match video code

Added in {{ parent() }} and added ending </script> and return false as indicated in the video code.
I actually just removed this and removed it from the stubs files (sha: 6978e87b0b88b92548097dd8931ddc5298067732). I *do* do this in the video, but it's technically not right (thought it doesn't hurt anything). Returning `false` is redundant because I have the `e.preventDefault()`. But, returning false *also* stops event bubbling (the same as `e.stopPropagation()` iirc), which we do *not* want here. It doesn't hurt anything, but stopping propagation can cause odd behavior later if you have some other JavaScript that's listening to a click event on an element that surrounds this one.

Regardless, I'm glad you added it so I could notice that I had this and remove it everywhere :).

Thanks!
