Kendo variables in Command section in a grid - kendo-ui

Question

I have noticed that it is possible to have some kendo logic and variables inside a template in the columns sections.
This is an example from my column section template
template: "#= myVariable# #if(myBoolean) {# <img src='/images/myImage.png' /> #}#"
Please do note that myVariable and myBoolean are variables (fields) of each row of the grid.
Unfortunately i tried the same under the command section in the template. I get the following error "ReferenceError: myVariable is not defined"
Is there any way to add variables in the command sections as it happens with the columns?

As far as I know using templates in columns.command is not even documented: although it works. And you can do things like:
columns : [
{
command: {
template : "# console.log('this', this); console.log('data', data); # toto"
}
},
...
]
or even like:
command: {
template : function (arg) {
console.log("this" ,this);
console.log("arg", arg);
console.log("data", data);
return "toto";
}
}
But what the template returns needs to be a string and in the console of your browser you will see that this is window, arg is the object command and data is an array containing grid data.
Although you can include extra arguments as:
command: {
template : function (arg) {
console.log("this" ,this);
console.log("arg", arg);
console.log("arg.a", arg.a);
console.log("data", data);
return "toto";
},
a: "extra argument"
}
Where I add an extra a argument that can be accessed via arg.a you still cannot get access to current row data since the element is still not inserted.
Instead of that what I do propose is doing something like:
columns : [
{
title: " ",
template: "#= myVariable# #if(myBoolean) {# <img src='/images/myImage.png' /> #}#"
},
...
]
You don't need to have it as command, right? Why do you need it as command?
