Double click on a folder not working in dhtml

Hi all,
I am using dhtmlx folders to display folders in my project. I am using an event called “ondblclick” .So, when i double click on folder it does not work properly as my code follows. Can any one help me in this.



It strongly recommended to use dhtmlxDataView instead of folders.
DataView provides all functionality of folders and a lot of extras, and has not above problem.
