URL not displaying change made with git.

I used git in the following steps.

This is a local directory on a Mac, with Yosemite, using the latest
git version.  The directory name is "development".

using eclipse I created a branch WO_1
I made a change to the file
eclipse indicates the change
I use the plus to add it to the Index
I commit the change
I go to the development directory using the terminal and checkout branch WO_1
using git status shows I am in branch WO_1
I used nano on the file to verify the change is there.

When I use my browser to bring up the site the change is not visible.
I have cleared the cache in the browser and have tried other browsers.

What I am I missing?
