popScene closing game entirely

[TheUnproPro]

For some reason my scene doesn't close properly, when I try to pop it it simply closes the entire game instead of returning to the scene it was previously at. Can someone help me?

EDIT: Sec, providing details.

Ok so basically, the scene is set up in this way:

function Scene_UppRomance() {
        this.initialize.apply(this, arguments);
    }
 
    Scene_UppRomance.prototype = Object.create(Scene_MenuBase.prototype);
    Scene_UppRomance.prototype.constructor = Scene_UppRomance;
 
    Scene_UppRomance.prototype.initialize = function() {
        Scene_MenuBase.prototype.initialize.call(this);
    };

    Scene_UppRomance.prototype.start = function() {
        Scene_MenuBase.prototype.start.call(this);
    };
 
    Scene_UppRomance.prototype.create = function() {
        Scene_MenuBase.prototype.create.call(this);
        //Some code here...
    };

this.pop.setHandler("cancel", this.popScene.bind(this));

closes the game completely instead of just popping the stupid scene. I'm calling the scene from
the menu, also tried from a plugin command.



--EDIT--

I've re-written it and now it works just fine. I have no idea why, though...
