选中复选框时输入框不更新sapui5

Question

我在 Web IDE 中创建了一个 table，它有一个复选框和输入框，当复选框被 select 时默认显示“100%”。在我从 json 添加数据之前它是有效的，但现在我将列列表项设为模板，从某些列的 json 接收数据，当 selecting 复选框。

现在显示的内容：

我想展示的内容：

如果我使用消息框之类的东西，它会在 select 选中复选框时正确输出。

sap.m.MessageBox.alert("100%")
sap.m.MessageBox.alert("0%")

我将事件绑定到select下的复选框。这是复选框的代码。

    percentCheck: function(oEvent) {
        //inputText is the input Text box  
        var inputText = this.getView().byId("inputPercent");
        var isSelected = oEvent.getParameter("selected");

        if (isSelected) {
            inputText.setValue("100%");
        } else {
            inputText.setValue("");
        }
    }

我认为最好更新模型而不是直接更改控件的值。这是一个例子 http://jsbin.com/yuhipop/edit?html,js,output

查看

sap.ui.define([
  'jquery.sap.global',
  'sap/ui/core/mvc/Controller',
  'sap/ui/model/json/JSONModel'
], function(jQuery, Controller, JSONModel) {
  "use strict";

  var oController = Controller.extend("myView.Template", {
    onInit: function(oEvent) {
      this.getView().setModel(new JSONModel([
        { name : "John", "company": "apple inc", selected: true, bonus: "100%" },
        { name : "Mary", "company": "abc inc", selected: true, bonus: "100%" },
      ]));
    },
    inputChanged: function(oEvent) {
      var cxt = oEvent.getSource().getBindingContext();
      var obj = cxt.getObject();
      obj.selected = (obj.bonus === '100%');
    },
    checkBoxChanged: function(oEvent) {
      var cxt = oEvent.getSource().getBindingContext();
      var obj = cxt.getObject();
      if (obj.selected) {
        obj.bonus = '100%';
      }
    },
  });

  return oController;
});

var oView = sap.ui.xmlview({
  viewContent: jQuery('#oView').html()
});

oView.placeAt('content');

这就是我能够用来处理数据的方法

查看：

<CheckBox id="checkEstimate" select="estimatePercentageSelect"/>
<Input value="{percent}" width="100%" id="inputPercent"/>

控制器：

estimatePercentageSelect: function(oEvent) {
//get parameter if checkbox is selected
var isSelected = oEvent.getParameter("selected");
//get source to bind
var cxt = oEvent.getSource().getBindingContext();

//if checkbox is selected, set property "percent" to 100%
if (isSelected) {
  cxt.getModel().setProperty("percent","100%",cxt);
  }
  else{
    cxt.getModel().setProperty("percent",null,cxt);
  }
}
