前台这样的： <li ng-click="$scope.getCoachsByExperience(1,3)">1-3年</li>
后台： $scope.getCoachsByExperience=(a,b)->

    value=[]
    for coach in coachs
      if coach.Experience >a and coach.Experience<=b
        value.push coach
    $scope.coachs=value
    $scope.totalCount=data.TotalCount

$scope.getCoachsByExperience(a,b)

报错：ReferenceError: a is not defined

然后现在报错是找不到：a，b

我的想法是点击1-3年就可以列出列表了

怎么把 <li ng-click="$scope.getCoachsByExperience(1,3)">1-3年</li> 当中的ng-click="$scope.getCoachsByExperience(1,3)" 1,3 传到 后台a，b 现在取不到a，b的值搞不来 ，哪里想错了，调试都跳不进去，求大神点拨
