Elysia cron module does not execute cron job automatically

I have installed the elysia cron module and setup the cron job. My module has a cron function test_cron() which inserts some data into a table.

This function lists in the elysia cron status page. I have setup the the default scheduled rule to */1 * * * * to run the cron after every minute.

When I click on the run infront of the test_cron() the cron runs and some data inserts into the database.

But this the manual method, I want to execute the cron after every minute therefore I defined the scheduled time for the test_cron(), but it does not executed automatically after every minute.

What should I do? Is there any other configuration which I should do to run the cron automatically?
