Bash-Completion, installed but not applied

Heyas

For my project TUI i had prepared bash completion.
Bash-completion works, at least if i source that file manualy.

However, when i'm installing it, it wont apply, not even for new opened terminals.
Allthough i had it working once, i dont get why it doesnt work now.

<...>
+ '[' '!' -d //share/bash-completion ']'
+ '[' -d //share/bash-completion/completions ']'
+ cp -a /home/sea/prjs/tui/compl/tui_compl.bash /share/bash-completion/completions
+ '[' 0 -eq 0 ']'
+ chown 0:0 //share/bash-completion/completions/tui_compl.bash
<...>

0 $ ll /share/bash-completion/completions/tar
-rw-r--r-- 1 root root 4.1K 23. Apr 2014  /share/bash-completion/completions/tar
0 $ ll /share/bash-completion/completions/tui_compl.bash 
-rw-r--r-- 1 root root 21K 29. Sep 20:29 /share/bash-completion/completions/tui_compl.bash
## This last is in the prj dir
0 $ ll compl/tui_compl.bash 
-rw-r--r-- 1 sea sea 21K 29. Sep 20:29 compl/tui_compl.bash

At first, the file was owned by me as user and didnt work, so i thought the issue was the user, so i've chowned it as root, to no help.
Also, there are tons of other files in the target folder where the script is copied to, so it must be at the right place.
But what am i missing?

Any ideas?
Thank you in advance

Also, removing "_compl.bash" has no effect.
It has the same permissions as the other scripts too.

So, in other words:
I wonder why the other bash completion scripts work, but mine not by placing it in that same folder?
