POST array in AJAX

My problem is 

jQuery.ajax({
    type: "POST",
    url: "../ajax/si-notificar_investigacion.php",
    data: {
        idincidente: $("#idincidente").val(),
        arrControlls : arrControlls
    },
    dataType: 'json',
    async: false,
    success: function(datos) {
        alert(datos);

    }
});

this is my ajax

Now I use arrControlls variable as array which is comes from another function

now if arrControlls is like 

[0] = "test1";
[1] = "test1";
[2] = "test1";

then it is okey I get this variable as an array in action page

BUT if I use value like this 

['sid_1'] = "test1";
['sid_2'] = "test1";
['sid_3'] = "test1";

then I do not get variable in action page WHY?

adding this lines for more detail

I am using jquery function for getting data 

function getAllControllValue()
{

    var  arrControlls = new Array();
    $("#container-div input").each(function(){
        arrControlls[$(this).attr('id')] = $(this).val();
    });
    return arrControlls;
}

Arrays are expected to have sequential, numeric indexes. That is what they are for. You can give them named properties, but tools designed to do something with the data in the array tend to ignore them.

Given an array anywhere in data, jQuery will only pay attention to the numeric indexes.

If you want to have named keys, then use a plain object.

Initialise arrControlls with {} not new Array().

User JSON.stringify like this: JSON.stringify(arrControlls)

jQuery.ajax({
    type: "POST",
    url: "../ajax/si-notificar_investigacion.php",
    data: {
        idincidente: $("#idincidente").val(),
        arrControlls : JSON.stringify(arrControlls)
    },
    dataType: 'json',
    async: false,
    success: function(datos) {
        alert(datos);

    }
});
