Problem in pushing git

Hi Im Lahiru im very new to git...Im using linux mint and i have problem 
using git...

1. I have a server and i create a new repo on it..buy this command
 #mkdir test.git
 #cd test.git
 #vi lahiru "add a line in it"
 # git add .
 # git commit -m"first git"

2. And i went to a client and i clone the project..
 #git clone ssh://user@mydomain.com
 #cd test
 #edit  file"lahiru"
 #vi poojitha "add a line to poojitha"
 #git add .
 #git commit -m"add a line on lahiru"
 #git push origin master

all these i showed to u is the way i have created, clone and push the 
repo's.. my problem is when i finishing the pushing part the changer's 
are not save on the main repo means on the server if i typed it showed 
is as delete line...."git status"

y is this not saving?

 git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#    modified:   lahiru
#    deleted:    poojitha


Im finding a solution from last few month
