ofxToggle addListener no matching member

hi,

i am trying to add listeners to ofxToggle using ofxGui. i found this helpful initially (https://forum.openframeworks.cc/t/vector-of-ofxgui-vector-listener-callbacks/20063) but i receive "No matching member for call to 'make_function' after creating my listener method. i'd like to add the toggle number to a list when it is 1 and erase it from the list if it is 0.

.h

ofxPanel testPanel;
ofxToggle testToggle[5];

vector<int> toggleList;

vector<int>::iterator toggleCntr;

void testPressed(ofxToggle &toggleNumber);

.cpp

void ofApp::setup(){

for(int i = 0; i < 5; i ++){
    testToggle[i].addListener(this, &ofApp::testPressed);
}

testPanel.setup("panel");
for(int i = 0; i < 5; i ++){
    testPanel.add(testToggle[i].setup("testToggle"));
}

}
//--------------------------------------------------------------
void ofApp::testPressed(ofxToggle &toggleNumber){

for(int i = 0; i < 5; i ++) {
    if(toggleNumber == 1) toggleList.push_back(toggleNumber);
    else if(toggleNumber == 0) {
        for(toggleCntr = toggleList.begin(); toggleCntr < toggleList.end(); ++ toggleCntr) {
            if(*toggleCntr == toggleList[i]) toggleList.erase(toggleCntr);
        }
    }
}

}

//--------------------------------------------------------------
void ofApp::draw(){
testPanel.draw();
}

how can i fix the call to the addlistener?

thanks in advance
