Comment nodes width

GoJS
1

Hello i try to implement a different node that will represent comment for other nodes.
The template map that i use is the following:

  this.diagram.nodeTemplateMap.add("comment",
    $(go.Node,
      { background: "transparent",},
      $("Shape", { fill: "white" }),
      $("TextBlock",
        { 
          margin: 3, 
          editable: true
        },
        new go.Binding("text").makeTwoWay()
        )
    ));

How can i make the width of the node to be max around 150 lets say, and if the text reach that width then break the lines of the text. also the same should happen if you resize the node.

This is my result from the above code :

    $(go.Node, "Auto",  // Shape surrounds TextBlock
      {
        background: "transparent",  // not needed because Shape is rectangular and has a solid fill
        maxSize: new go.Size(150, NaN)  // limit width
       },
      $("Shape", { fill: "white" }),
      $("TextBlock",
        {
          stretch: go.GraphObject.Horizontal,  // stretch to panel's width
          margin: 3, 
          editable: true
        },
        new go.Binding("text").makeTwoWay()
        )
    )
