Liferay.on('tempFileRemoved',function()) not works

[Madasamy P, modificado hace 6 años.]

Here I used tempFileRemoved for every single file deleted it redirected to the function getFiles
But when I was deleted the last file tempFileRemoved not works

Liferay.on(
'tempFileRemoved',
function(event) {
var values = A.all('input[name=<portlet:namespace />selectUploadedFileCheckbox]:checked').val();
var reference = '<%=reference%>';
Liferay.Util.getOpener().getFiles(values,reference);
}
);
What is the problem
