doesn't work well with ajax. (select2 v4.0.3)

[linbren]

`$("#sajaxtree").select2tree({
			language : "zh-CN",
			multiple : "multiple",
			allowClear : true,
			ajax : {
				url : $webPath + 't.do?getFuncList',
				dataType : 'json',
				delay : 250,
				data : function(params) {
					var query = {
						search : params.term,
						page : params.page || 1,
						rows : 30,
						key : 'EXPERT_TEAM'
					}
					// Query paramters will be ?search=[term]&page=[page]
					return query;
				},
				processResults : function(data, params) {
					params.page = params.page || 1;
					var rows = data.rows;
					var newrows = [];
					for ( var i in rows) {
						var row = rows[i];
						/* 				row.id = row.funcCode;
										row.text = row.funcName;
										row.parent = row.parentCode; */
						newrows[i] = new Object();
						newrows[i].id = row.funcCode;
						newrows[i].text = row.funcName;
						newrows[i].parent = row.parentCode;
					}
					console.debug("ajax返回的对象是:")
					console.debug(newrows)
					return {
						results : newrows,
						pagination : {
							more : (params.page * 30) < data.total
						}
					};
				},
				cache : true
			},
			escapeMarkup : function(markup) {
				return markup;
			},
			templateResult : formatTreeRepo,
			templateSelection : formatRepoSelection
		});`

getFuncList return a simple json string of bean array .
it was display as a simple select2 object ,but not tree in droplist.
