# Option: init_instance_callback

This option should contain a function name to be executed each time a editor instance is initialized. The format of this function is: initInstance(inst) where inst is the editor instance object reference.

### Example of usage of the init_instance_callback option:

    function myCustomInitInstance(inst) {
        alert("Editor: " + inst.editorId + " is now initialized.");
    }

    tinyMCE.init({
        ...
        init_instance_callback : "myCustomInitInstance"
    });
