External function call c3_callFunction not calling a function

Hello guys.

I try to call a function on html file with c3_callFunction.

But the function is not called and when I test run in console debug it return 0.

function I try to call

This is when I try run c3_callFunction in other project and worked

Does the project use the legacy Function plugin? If so then for backwards compatibility c3_callFunction() will call a function in the legacy Function plugin instead of a built-in function. To make sure it calls built-in functions, remove the legacy Function plugin.

you're right, there is function plugin in this project.

by the way, I had other solution for this. Im affraid the project become broken if I remove it.

thanks Ashley
