Commit eclipse to IBM DevOps

I’m relatively new to IBM Bluemix. So i am running a Speech to Text java project at Eclipse, using instructions from this link:

The code is running fine at Eclipse, but if you see the 3rd last step at the instruction, they are connecting the eclipse code to Devops training using “Commit and Push”. I tried doing that step and Pushed from eclipse. also i could see the pushed files at my Git section of DevOps Services. Image here But i do not know to proceed further. as in; how to trigger a new deployment process at DevOps Services. When I do build and Deploy, its deployed successfully but it does not show any result when I do Open Deployed app link. Can anyone please help and let me know what mistake i’m doing here.
