Don't understand how to bind user click to a specific object within datafraame

I'm new to Python and I have the following code . When executed I get a GUI which allows me to check in /Out a checkbox . I have created an if statment to record the status of the clicking , however I don't understand how to bind the checkbox to a specific object within a dataframe (Pandas).The dataframe includes a list of objects that can user choose from ,so when the application save the data to csv file only the selected data will be saved . Right now I can't make it work . All the fields are saved to the csv file ,always .

Can you help me to understand what to do to make to be selectable ? Thx .
