I cannot perform 2 functions at the same time

Assuming that frm_order is a form, unless you've defined that elsewhere, you need to do $("#frm_order") to access it. There would be a syntax error preventing any further execution. Hence, nothing is done.

The second function you want to run, just does the same thing as the first? Clicking a submit button inside a form, is just $("#frm_order").submit() with extra steps.
