Building basic javascript object array

I'm not sure if it's because it's late or what, but I seem to be having a really difficult time tonight thinking through structuring a pretty basic object array and building it.

What I'm trying to do is gather a list of text field id's and put them into a group variable;

Example 

groupA:{year, make, model}
groupB:{color,body}

I'm not sure how to structure my main group object. I'm not sure if it should be using an array or not. Below is my first attempt

group = {groupA:{"year","make","model","trim"},groupB:{"body","color","transmission"}}

I attempted building my group object like so, but I really feel I'm doing it all wrong. 

  //Class variable
  Var group = {}

  //this method is called for every textfield
  selectGroup = function(spec) {
    //Group id is the group the field is assigned to, example groupA, or groupB
    var groupId = spec.groupId;

    //I'm checking to see if groupId exist in group object, otherwise I add it. 
    if (!group.hasOwnProperty(groupId)) {
        var obj = {};
        obj[groupId] = [];
        group = obj;
    }
    //spec.id is the field id, example make, model
    group[groupId].push(spec.id);
};

If anybody could help me fix this all up, I'd greatly appreciate it. Thanks in advance.

Here you go working fiddle

var group = {};

//this method is called for every textfield
selectGroup = function (spec) {
    //Group id is the group the field is assigned to, example groupA, or groupB
    var groupId = spec.groupId;

    //I'm checking to see if groupId exist in group object, otherwise I add it. 
    if (!group.hasOwnProperty(groupId)) {
        group[groupId] = [];
    }
    //spec.id is the field id, example make, model
    group[groupId].push(spec.id);
};

Assuming you want output like this,

group = {groupA:["year","make","model","trim"] , groupB:["body","color","transmission"]},

You can do,

var group = {};

if (!group.hasOwnProperty(groupId)) {            
    group[groupId] = [];            
}        
group[groupId].push(spec.id);
