func_two does not trigger in javascript [duplicate]

Question

I have javascript script code here. When I execute my code as it is then it does not trigger func_two function. But when I change following code in func_one

    if (this.remove) {
        this.func_two;
    }

to this

    if (this.remove) {
        this.func_two();
    }

Then it does trigger second function. But I want to trigger it this way this.func_one. IS it possible to do it this way? How?

I really don't get "I want to do it this way" at all. Calling a function is done by writing () after it. If you want to do it another way, you have to find another programming language that agrees with you. — Jon

There is a way in backbone for example this.collection.each(this.render, this);. this.render is a function which is called without brackets. — Om3ga

@x4ph4r: No, the function is not called in this case. You are just passing a reference to the function to .each and .each calls it internally. — Felix Kling

@Alp I was trying to solve stackoverflow.com/questions/16163934/… in different way but now it is not possible to do it this way, I guess. — Om3ga

You have to put () when you call a function, you can't just, out of nowhere, decide that you want it to work another way.

Take a look at this answer, it may help you.

this.func_two;

This statement return the function. It does not call the function.

To call the function you have to add () at the end.

or you have to do it like:

f2=this.func_two;
f2();
