Fiori Tile not displaying the summary count

Hi Friends,

I have created custom Z odata service and developed UI5 application based on oData service. I am not seeing the summary information on the tile.

For example , when I look at standard SAP FIORI leave approval, which displays as 'Pending Approval' 20

In my custom scenario , I am not seeing any number here, it is displaying the tile of the tile. Attached screen. To get the count here like the number of items etc...what I need to change in my custom oData service?

Thanks
