Changing function properties from outside might be doable, but it's pretty much goes agains the idea of functions.

In my opinion - unless you will publish your code so say otherwise - you might be attempting the solution from the wrong direction.

Try to share the problem you are trying to solve, and not the solution you cant implement.

Happy Coding!

why not from inside? – Itamar Sep 26 '18 at 12:33
it is on the wordpress plugin file, i am just modifying it from the outside for adding an additional function. The plugin will work normal only after modifying this counter – junaid TK Sep 26 '18 at 12:38

i have assigned the self invoked function to a variable and set some return value from the function.

var assigned_variable = (function( $ ) {

  function test_function(counter){
    "add your code for changing the counter"
  }

  return {
    test_function : test_function,
  }

})(jQuery);

function Innerfunction(counter){
  assigned_variable.test_function(counter);
}

Now we can access the Innerfunction from outside of the file. We can predefine the required changes in the "test_function" for the variable counter
