[Fixed]-AJAX dont update page

I think that your problem is here
First check this line
File "C:\Users\Nurzhan\PycharmProjects\RMS\project\views.py", line 252,

data['html_function'] = render_to_string('project/function_list.html', {'functions': functions, 'request_user_is_business_analyst': request_user_is_business_analyst})

and print request_user_is_business_analyst to see what returns

EDIT:
Solve:
must be like this:

data['html_function'] = render_to_string('project/function_list.html', {'functions': functions, 'request_user_is_business_analyst': request_user_is_business_analyst, 'project':project, 'function':function})
