ListView Android - CheckBox for disabling Editext

I have i ListView that is made like this:

CheckBox - ImageView - TextView - EditText

Now the listView works it remeber the entries and it doesn't mix editText when scrolling, but now i can't do the same with checkbox. Checkboxes do not want to disable the right editext and the same when they need to renable it. I've tried a lot of possibilities but i have no success, what i'am doing wrong?

        return getCount();
    }

        return position;
    }

}

i've set the listener on both the checkbox because i want to try what will happen, but i'have got the same result. This is my ArrayAdapter for the ListView Thanks
