Loop through checkbox in Oracle APEX 4.2 (w. JQuery Mobile)

Question

I want to implement a question-answer system an ORACLE APEX Application that uses the JQueryMobile Framework. Basically, a question text and a report containing the possible answers is shown on a page. An answer can be selected by clicking on the checkbox. After hitting the submit button, the selected checkboxes containing the Answer Text, an answer_id and the current session_id are to be inserted into a table within the database.

Within Oracle APEX 4.2, I am using a classic report to achieve this. Thich is actually a bad solution, because the checkboxes within the report are shown as simple HTML checkboxes, instead of neat JQueryMobile checkboxes). Anyway, this is my current solution:

Is use this code for creating the classic report:

SELECT 
  APEX_ITEM.CHECKBOX(1,answer_id),
  answer_id,
  answer_text
  FROM ANSWERS
  WHERE question_ID = :P10_Question_ID;

The insert of the data is done via the on submit process "On Submit - After Computations and Validations"

This is the code for the on submit process:

DECLARE
var_session_id NUMBER := :P0_SESSION_ID;
BEGIN
    FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
        INSERT INTO STUDENT_ANSWERS
        (answer_id, answer_text, session_id)
        SELECT a.answer_id, a.answer_text, var_session_id
        FROM ANSWERS a
        WHERE a.answer_id = APEX_APPLICATION.G_F01(i)
    END LOOP;
     COMMIT;
    END;

But this solution does not work. Instead, nothing is inserted into the database.

I don't know why the process is not inserting into the database, maybe there is something wrong with this line here WHERE a.answer_id = APEX_APPLICATION.G_F01(i) ?

I even tried a simple update process for testing purposes, but this doesnt work either:

BEGIN
    FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
        UPDATE STUDENT_ANSWERS
        SET text = APEX_APPLICATION.G_F03(APEX_APPLICATION.G_F01(i))
        WHERE am_id = APEX_APPLICATION.G_F02(APEX_APPLICATION.G_F01(i));
    END LOOP;
    COMMIT;
END;

Can anybody tell me how to loop through a checkbox within ORACLE APEX 4.2 and how to insert the values ANSWER_ID, ANSWER_TEXT and SESSION_ID into the table STUDENT_ANSWERS after hitting the submit button? If you would know how to do it without using a report but a simple checkbox, this would be even more helpful for me!

Do your checkboxes reside within the main form tag of your page (you can check this by viewing the page source at runtime)? The Fnn elements must reside within a HTML form to be submitted to the server.

Do you know if the G_Fnn array is even populated?
