How to open/show CellEditor of Alloy Datatable manually?

I'm writing a code , so that I can change column's editor manually . I'm able to set editor event on double click event ('dblClick') . When I click on cell, effect is observe on next click . What is missing ? Or How can open/show editor manually ?

My code is like .......

table.delegate('dblclick', function(e) {
    var target = e.currentTarget; 
    var model = table.getRecord(target.get('id'));
    var type = model.get('type');
    var column = this.get('columns.value'); 
    column.editor = editors[type];
    this.showCellEditor(target); 
},'tr', table);

this.showCellEditor(target); --> this method is of YUI (Yahoo's UI) . Is any method is resemble to this one in Alloy UI ?

Solution

Instead of selecting an editor on the fly, why not group similar data in the same column so that the same editor can be used?

var columns = [{
    editor: new Y.TextAreaCellEditor(),
    key: 'name'
}, {
    editor: new Y.DateCellEditor({
        dateFormat: '%m/%d/%Y'
    }),
    key: 'birthday'
}];

If you group the data like that, then you can change the editEvent of the dataTable to dblclick like so:

var dataTable = new Y.DataTable({
    // ...
    editEvent: 'dblclick'
}).render('#dataTable');

Here is a working example:

YUI().use('aui-datatable', function(Y) {

  var columns = [{
    editor: new Y.TextAreaCellEditor(),
    key: 'name'
  }, {
    editor: new Y.DateCellEditor({
      dateFormat: '%m/%d/%Y'
    }),
    key: 'birthday'
  }];

  var data = [{
    birthday: '9/9/1999',
    name: 'Jonathan Smithy'
  }, {
    birthday: '10/10/1990',
    name: 'Bob Duncan'
  }];

  var dataTable = new Y.DataTable({
    columnset: columns,
    recordset: data,
    editEvent: 'dblclick'
  }).render('#dataTable');

});

<div id="dataTable"></div>

If you must dynamically choose and display the editor, I'd recommend taking a look a the getEditor(record, column) method of A.DataTable.CellEditorSupport. I was unable to get getEditor() to work, but I'd assume that if you can get it working, you could do something like getEditor(data[1], column[0]).show().
