Temp im must fix on client-side by this code

Call setTimeout onClick lbtSave, if CKE destoyed then re-load it.

setTimeout(function(){
//ko có _busyRequest sẽ gây conflic CKE
if(_busyRequest) return;

console.log('click Save delay 100');
if(CKEDITOR && CKEDITOR.instances
&& typeof(CKEDITOR.instances.<%=txtContent.ClientID%>_txtContent)== 'undefined'
&& typeof(LoadCKEditorInstance_<%=txtContent.ClientID%>_txtContent)!= 'undefined')
{
console.log('reloadCKE');
LoadCKEditorInstance_<%=txtContent.ClientID%>_txtContent();
}
}, 100);
