Use flx.create_element to create a label in the for loop, bind the onclick event, and dynamically transfer parameters. lambda fun error about flexx

This is a consequences of how closures work; the lambda loads the check_id from the outer scope, which will be left at whatever was its last value.

There are a few ways to fix this:

• Classic closure solution: use a helper function to create a scope that holds check_id. E.g. a function create_my_element(check_id) that produces index_id.
• Store self.checkd_fun on something like window.my_app_checkd_fun, and then "onclick": f"window.my_app_checkd_fun('{check_id}')". This works well when self is some sort of global object, but may get tricky if its not.
• Use lambda e: self.checkd_fun(e), in checkd_fun check e.target to get the element. Store check_id on the element.
