Help to applya function ina checkbox

[Sami Artur]

I am trying to put a function in a checkbox to execute a opentype feature.
This opentype feature isn't in Indesign UI but You can access using a script

I don't know what is wrong.
Please any help would be great:

/@targetengine "OpenTypeFeatures"
var palette = new Window("palette");
palette.text = "Character Variants";
palette.orientation = "column";
palette.alignChildren = ["center","top"];
palette.spacing = 30;
palette.margins = 60;

// GROUP1
// ======
var group1 = palette.add("group", undefined, {name: "group1"});
group1.orientation = "row";
group1.alignChildren = ["left","center"];
group1.spacing = 10;
group1.margins = 0;
group1.alignment = ["center","top"];

var checkbox1 = group1.add("checkbox", undefined, undefined, {name: "checkbox1"});
checkbox1.text = "CV01";
checkbox1.alignment = ["left","top"];
checkbox1.value = false

checkbox1.onClick = function () {
if (checkbox1.onClick() == true) {
checkbox1.value = true;
checkbox1.checked = true;
if( app.selection[0].hasOwnProperty("opentypeFeatures"))
app.selection[0].opentypeFeatures=[["cv01",1]];
}
else {

app.selection[0].opentypeFeatures = []; // reset to nothing
}
}
var convert_button1 = palette.add ("button", undefined, "OK");
convert_button1.onClick = function () { palette.close(0) }

palette.show();

Hi, Try below

#targetengine "session"

var palette = new Window("palette");
palette.text = "Character Variants";
palette.orientation = "column";
palette.alignChildren = ["center", "top"];
palette.spacing = 30;
palette.margins = 60;

// GROUP1
// ======
var group1 = palette.add("group", undefined, { name: "group1" });
group1.orientation = "row";
group1.alignChildren = ["left", "center"];
group1.spacing = 10;
group1.margins = 0;
group1.alignment = ["center", "top"];

var checkbox1 = group1.add("checkbox", undefined, undefined, { name: "checkbox1" });
checkbox1.text = "CV01";
checkbox1.alignment = ["left", "top"];
checkbox1.value = false

checkbox1.onClick = function () {
    if (checkbox1.value == true) {
        alert("Executed");
        if (app.selection[0].hasOwnProperty("opentypeFeatures"))
            app.selection[0].opentypeFeatures = [["cv01", 1]];
    }
    else {
        app.selection[0].opentypeFeatures = []; // reset to nothing
    }
}
var convert_button1 = palette.add("button", undefined, "OK");
convert_button1.onClick = function () { palette.close(0) }

palette.show();

The following statement is wrong

if (checkbox1.onClick() == true) {

instead of this you should check if value of checkbox is true then excute your code.

Thank You Charu, it works but I can't remove the opentype feature after checkbox is checked.
Could You help me one more time, please?
Best Regards
Sami
