polymer-3.x - Polymer-3.x ..无法通过对象引用从JSON绑定值到paper-toggle-button(Polymer-3.x.. Can't able to bind value from the JSON through object reference to the paper-toggle-button)

Question

 //Properties drivingEligibility:{type:Boolean,notify:true} //EventListener driving(){ if (this.$.drivingEligibility.checked == true) {this.drivingEligibility = true; console.log(" drivingEligibility.value in if :" +this.drivingEligibility); }else{ this.drivingEligibility = false; console.log(" drivingEligibility.value in else :" +this.drivingEligibility); } } 

 HTML Code <paper-toggle-button name="drivingEligibility" id="drivingEligibility" class="float-right" checked="{{drivingEligibility}}" on-change="driving"></paper-toggle-button> 

Data is saving in the correct format.. but data is not binding to the element(paper-toggle-button)

(数据以正确的格式保存..但数据未绑定到元素（纸张切换按钮）)
