Vue Watch not triggering

Trying to use vue watch methods but it doesn't seem to trigger for some objects even with deep:true.

In my component, I recieve an array as a prop that are the fields to create the following forms. I can build the forms and dynamicly bind them to an object called crudModelCreate and everything works fine (i see in vue dev tools and even submiting the form works according to plan)

But I have a problem trying to watch the changes in that dynamic object.

  <md-input v-for="(field, rowIndex) in fields" :key="field.id" v-model="crudModelCreate[field.name]" maxlength="250"></md-input>

   ...

   data() {
      return {
         state: 1, // This gets changed somewhere in the middle and changes fine
         crudModelCreate: {},
      }
   },
   ...
   watch: {
        'state': {
            handler: function(val, oldVal) {
                this.$emit("changedState", this.state);
                // this works fine
            },
        },
        'crudModelCreate': {
            handler: function(val, oldVal) {
                console.log("beep1")
                this.$emit("updatedCreate", this.crudModelCreate);
                // This doesn't work
            },
            deep: true,
            immediate: true
        },
    }
