Why DSM node not working correctly

General

Why this node-red-contrib-dsm not working? I try to use it to count rf button clicks. On DSM input i get coun 1 or 2 or 3.

{
    "triggerInput": "count",
    "stateOutput": "payload",
    "currentState": "depressed",
    "states": {
        "pressed-once": {
            "1": "pressed-once"
        },
        "pressed-twice": {
            "2": "pressed-twice"
        },
        "pressed-thrice": {
            "3": "pressed-thrice"
        },
        "depressed": {
            "0": "depressed"
        }
    }
}
