DataGrid Dojo Not Working in Widget - dojo

Question

I have a widget on dojo, but it does not display the datagrid. If I make the example outside the widget works. I see the code by firebug, you can not mistake, however, I can see the div inspect and there is nothing inside. The Builder runs, but does not load the grid in div.
Widget.js
define([ "dojo/_base/declare",
"dojo/text!./FormularioQCI.html",
"icm/base/_BaseWidget",
"dojo/store/JsonRest",
"dojo/store/Memory",
"dojo/store/Cache",
"dojox/grid/DataGrid",
"dojo/data/ObjectStore"
],
function(declare, template, _BaseWidget, JsonRest, Memory, Cache, DataGrid, ObjectStore){
return declare("icm.custom.pgwidget.formularioQCI.FormularioQCIWidget", [_BaseWidget], {
templateString: template,
widgetsInTemplate: true,
constructor: function(){
alert("X");
myStore = dojo.store.Cache(dojo.store.JsonRest({target:"rest/formularioQCI/get"}), dojo.store.Memory());
grid = new dojox.grid.DataGrid({
store: dataStore = dojo.data.ObjectStore({objectStore: myStore}),
structure: [
{name:"State Name", field:"name", width: "200px"},
{name:"Abbreviation", field:"abbreviation", width: "200px", editable: true}
]
}, "target-node-id"); // make sure you have a target HTML element with this id
grid.startup();
alert("Y");
dojo.query("#save").onclick(function(){
alert("X");
dataStore.save();
});
var id = 0;
dojo.query("#add").onclick(function(){
dataStore.newItem({
name: "col2-" + id,
abbreviation: "col3-" + id
});
id++;
});
},
/**
* #private destroys this widget
*/
destroy: function() {
//Do any custom clean up here
this.inherited(arguments);
}
});});
Widget.html
<div style="width: 100%; height: 100%;">
<div id="target-node-id">
</div>
<button id="save">Save
</button>
<button id="add">Add Linha
</button>
</div>

Answer 1

you need to write you code in the postCreate function.
Simplest way would be to replace the constructor keyword with postCreate.
The reason being that the "target-node-id" will not be available until the postCreate function call.
postCreate: function(){
this.inherited(arguments);
// Rest of your code here.
alert("X");
...
}
