postrender event from Vectorlayer does not work with openlayers 6

We are using openlayer 6.3.1 und want to use "postrender" event from Layer Api, but it does not work right.

The code is like this:

vectorLayer.on("postrender", this.moveFeature);
......
moveFeature: function (event) {
    console.log(event);
...

The console log message will not show.

But if i change the code to:

vectorLayer.on("postrender", console.log("test"));

the log message "test" will be shown in console,

If i change the code to:

vectorLayer.on("postrender", function(evt) {
    console.log(evt);
});

there is also no console messages, what could be the problem? Our project is backbone basis, and we use many backbone event, i dont know if it make some troubles.

Your layer is probably already rendered. You can call render on the map after declaring your event.

function animate(event) {
  // your logic here

  // Rerender to loop
  map.render();
}
this.vectorLayer.on('postrender', animate);
map.render();
