No binding support for File Upload control

<div ng-controller="form-cntlr">
        <form>
             <button ng-click="selectFile()">Upload Your File</button>
             <input type="file" style="display:none" 
                id="file" name='file' onchange="angular.element(this).scope().fileNameChanged(this)" />
        </form>  
    </div>

instead of

 <input type="file" style="display:none" 
    id="file" name='file' ng-Change="fileNameChanged()" />

can you try

<input type="file" style="display:none" 
    id="file" name='file' onchange="angular.element(this).scope().fileNameChanged()" />

Note: this requires the angular application to always be in debug mode. This will not work in production code if debug mode is disabled.

and in your function changes instead of

$scope.fileNameChanged = function() {
   alert("select file");
}

can you try

$scope.fileNameChanged = function() {
  console.log("select file");
}
