function FormController(){
this.user = {
name: "",
valide: true,
data : "TEST"
}
}

FormController.prototype = {
fetchdata: function () {
this.user.data = "Loading...";
var d = loadJSONDoc("http://search.twitter.com/search?
q=artyprog");
var x = this;
var gotMetadata = function (meta,ctx) {
this.user.data = meta.results[0].text;
};
var metadataFetchFailed = function (err) {
alert("The metadata for MochiKit.Async could not be
fetched :(");
};
d.addCallbacks(gotMetadata, this);
d.addErrback(metadataFetchFailed);

},
save: function () {
alert(angular.toJson(this.user));
}
}
