Alternative for AW.object(this.element().id)

Hello I am interested in using the same function handlers for all the grids.
so instead of using "myGrid" as the object I can use AW.object(this.element().id) as shown below

var myGrid = new AW.Grid.Extended; 
...
myGrid.onCellTextChanged = cellTextChanged;
myGrid.onCellEditStarted = cellEditStarted;
...

example:

function cellTextChanged(text, column, row)
{
  AW.object(this.element().id).setFooterText(text, column, 1);
  AW.object(this.element().id).getFooterTemplate(column, 1).refresh();
};

instead of

function cellTextChanged(text, column, row)
{
  myGrid.setFooterText(text, column, 1);
  myGrid.getFooterTemplate(column, 1).refresh();
};

I have no idea which are the system resources used by this method and my question is that is it suitable for using it.
If no, which are the alternatives ?

I also want to get the instance of the input text used by AW to edit the cell. For now I use:

this.element().getElementsByTagName('INPUT')[0];

as in

function cellEditStarted(text, column, row)
{
   var cellEd = this.element().getElementsByTagName('INPUT')[0];
        cellEd.setAttribute('maxLength',5);// limit to 5 chars
        cellEd.name = cellEd.id;//for viewing in FF Page information-Forms 
};

which reads though the entire grid / spans.

PS: For the demonstration I have used a 2-footered Extended Grid with editable rows / cells and when editing I display the current text value to the 2nd footer cell that coresponds to that column... as testing purposes

Thanks in advance

Do not use AW.object(this.element().id) - just use this instead. All control event handlers are executed in such way that keyword this refers to the control itself.

function cellTextChanged(text, column, row)
{
  this.setFooterText(text, column, 1);
  this.getFooterTemplate(column, 1).refresh();
}; 


var myGrid = new AW.Grid.Extended; 
...
myGrid.onCellTextChanged = cellTextChanged;
myGrid.onCellEditStarted = cellEditStarted;
...

Note, that AW does not use INPUT tag for cell editing in IE (uses SPAN with contentEditable=true). You can get access to the editor tag this way -

function cellEditStarted(text, column, row)
{
   // 'this' refers to the grid object
   var cellObject = this.getCellTemplate(column, row);
   var textObject = cellObject.getContent("box/text");
   var textElement = textObject.element();
   ...
};
