After retrieve data and use Y.DataTable.addRow to add data, then I use DataTable's model to set value, this dose not effect on the web page. This is appeared when I upgrade YUI to 3.6.0.

Example: table is a instant of Y.DataTable
table.addRow(....); //then the page coule display the table's data
table.data.item(0).set("no", 1); //the page coule not display 1 at first row with column 'no'
alert(table.data.item(0).get("no")); //the model is do set to 1

So what's the problem above when upgrade YUI to 3.6.0, this is correct when use YUI 3.5.1

I found the problem occurred by DataTable's recordType attribute:
YUI().use( "datatable", "cssfonts", function(Y){
Y.one("body").addClass("yui3-skin-sam");
var some_data =[
{no:0, fname:'jesse', status:1},
{no:0, fname:'gustavo', status:0},
{no:0, fname:'walter', status:1},
{no:0, fname:'hank', status:1},
{no:0, fname:'tuco', status:0}
];
var dtable = new Y.DataTable({
columns: ['no','fname','status'],
data: some_data
}).render('#divTable');
//notice this sentense
dtable.set("recordType", dtable.get("columns"));
Y.one("#btnChange").on("click",function(){
var modelList = this.data;
for (var i = 0; i < modelList.size(); i++) {
modelList.item(i).set("no", i);
}
},dtable);
});
So when you click the button, the column 'no' value has no changed.
This is happend when set the recordType, using datatable's Model.set or setAttrs had no effect, if omitted, then could set value by using Model.set.(Only YUI 3.6 occurd this problem)
