Workflow not working on created tasks from agile board

Hi,

I have the following workflow rule in place and it works fine when I create an issue, the problem I have is when creating tasks I want the same workflow to apply which is not happening.  I want to set the assignee to the project lead and make sure the state is new.  Can anyone show what I am doing wrong?

rule Add assignee on creation

when isReported() {
    Assignee = project.leader;
    State = {New};
}
