Issues with grabbing text from a text input and using a button to send it to a container (Bootstrap)



I'm having some trouble with a button click event and taking the text from a text input and sending that to a container (as if it were a chat program, but in this version of it there is no server yet). It should function like this jsfiddle, only with a visible container to append the text into. Here is a link to the full code that I'm currently debugging: Google Doc. All help is appreciated. Thanks.
