Weinre not working, trying to debug?

I think I may be missing something, but I have installed the .apk on my android tablet with the script

<script src="http://localhost:8080/target/target-script-min.js#anonymous"></script> 

in the header.

I decided to try running it locally following http://forums.adobe.com/docs/DOC-2623. I went to "localhost:8080" and weinre is installed, but I still get the same thing "target not found".

I think I am missing a step, or I am not completely understanding how it connects to my app?

I have also tried building it via build.phonegap.com enabling debug mode, then installing the apk then clicking debug, gosh the steps are nice and easy but I can't get it to work.

I have to be missing something, so I hope someone can help me understand what I am missing.

Solved: Thanks to @Christian Kuetbach following his answer helped, let me add a few things just in case someone else has this issue.

1. I made sure the script weinre gives you to add is loaded last, I put it at the very bottom, because I figured it should load after everything. Just did this to make sure.

2. Make sure to connect to weinre properly, @Christian Kuetbach says it --boundHost -all- but I had to enter it like this weinre --boundHost -all- maybe adding the weinre is an obvious thing, but it could cause confusion, so make sure to do that I am running on win8 if that makes a difference.
