在angularjs中传递选项的值

Question

我正在尝试将所选选项的值传递给我的ng更改功能。下面显示的是我的代码

 <select ng-model="this.value" ng-change="showExecutionStepOptions(study.id,acase.id,this.value)">
                                        <option value='acase.executionSteps[0].id' selected=selected>TOPPER</option>
                                        <option value='acase.executionSteps[1].id'>RSC</option>
                                        <option value='acase.executionSteps[2].id'>SPD</option>
                                        <option value='acase.executionSteps[3].id'>SFT</option>
                                        <option value='acase.executionSteps[4].id'>LMP</option>
                                     </select>

有人可以告诉我什么是正确的语法？
