For some reason ramp function in <transition> is not updating datamodel. Otherwise our solution works

index.js

const scxml = require("@scion-scxml/scxml");
const core = require("@scion-scxml/core");

let action = {
  "http://www.NotRealURL.de": {
    wait: function (action, builder) {
      const tic = new Date();
      while (true) {
        const toc = new Date();
        const duration = toc - tic;

        if (duration >= parseInt(action.duration.replace("ms", ""))) {
          console.log(duration + "here");
          break;
        }
      }

      return "something";
    },

    expect: function (action, builder) {
      let expr = builder.generateFnCall(
        builder.generateAttributeExpression(action, "expr")
      );
      return `if(${expr}){
            this.log('Expect Action Success');
        } else {
            this.log('Expect Action Failed');
        }`;
    },
    ramp: function (action, builder) {



        return `this.log(${action.dataid}.value); 
        for (let i =0 ; i < 10; i++) { 
          let temp=${action.dataid}.value + parseInt(${action.slope});
            ${action.dataid}.value = temp;
           // this.log(${action.dataid}.value);
          }
          this.log(${action.dataid}.value);   


          `;
    }
  }
};

scxml.registerCustomActionTags(action);
scxml.pathToModel(
  "rampINPUT.scxml",
  function (err, model) {
    if (err) throw err;
    model.prepare(function (err, fnModel) {
      if (err) throw err;
      //instantiate the interpreter
      var sc = new core.Statechart(fnModel);
      //start the interpreter
      sc.start();
    });
  }
);
