Missing something with lasso and marko-widgets

[LucasBadico]

So guys, I'm in a bit little nightmare here. Starting using makoJs and Marko-widgets loving so far. But...

This is the thing I follow the organization of some samples and integrate with the lassoJS. So in the lasso way of doing things I do not get to implement the define component methods.

So what I need to accomplish:

module.exports = require('marko-widgets').defineComponent({
    template: require('./template.marko'),
 
    getInitialState: function(input) {
        return {
            name: input.name,
            selected: input.selected || false;
        }
    },
 
    getTemplateData: function(state, input) {
        var style = ;
 
        return {
            name: state.name,
            color: state.selected ? 'yellow' : 'transparent'
        };
    },
 
    handleClick: function() {
        this.setState('selected', true);
    },
 
    isSelected: function() {
        return this.state.selected;
    }
});

My Marko file is being writing as this:

import './style.css'

static function getClassNameForValue(value) {
    if (value < 0) {
        return 'negative';
    } else if (value > 0) {
        return 'positive';
    }
}

class {
    onInput(input) {
        var value = input.value || 0;

        this.state = {
            value: value
        };
    }

    handleIncrementClick(delta) {
		
        this.state.value += delta;
		var value = this.state.value;
		
		
		var send = {
			value:value
		}
		console.log(value);
		$.post( "/tryPost", send,function( data ) {
			console.log(data);
		});	
    }

    handleInputKeyUp(event, el) {
        var newValue = el.value;
        if (/^-?[0-9]+$/.test(newValue)) {
            this.state.value = parseInt(newValue, 10);
        }
    }
}

$ var value=state.value;

<div class=['number-spinner', getClassNameForValue(value)]>

    <button type="button" onClick("handleIncrementClick", -1)>
        -
    </button>

    <input type="text" value=state.value size="4"
        onKeyUp("handleInputKeyUp")>

    <button type="button" onClick("handleIncrementClick", 1)>
        +
    </button>

</div>

Edit:
So I was thinking, know what version of those modules I'm using could help.

   "lasso": "^2.11.3",
    "lasso-less": "^2.4.3",
    "lasso-marko": "^2.2.2",
    "lodash": "^4.17.4",
    "markdown-js": "0.0.3",
    "marked": "^0.3.6",
    "marko": "^4.0.0-rc.18",
    "marko-widgets": "^6.6.0"

So how, to implement the listener for events of the lifecycle?
