Haxe js webgl issue.

I have very strange problem with setting texture from file. If I use Uint8Array instead (commented in code below) everything is ok and works. What important did I missed? Program always reaches "onload" so file is ok and it loads! Using more "untyped" constructions in various suitable places does not helps me.

public function addTexture(): Dynamic

    {

        var image: Image = untyped __js__("new Image()");

        image.src = "textures/tex0.png";

        image.onload = function(e: Event)

        {

            texture = gl.createTexture();

            gl.bindTexture(gl.TEXTURE_2D, texture);

            gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.NEAREST);

            gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR);

            gl.texParameteri(gl.TEXTURE_2D, gl.GL_TEXTURE_WRAP_S, gl.CLAMP);

            gl.texParameteri(gl.TEXTURE_2D, gl.GL_TEXTURE_WRAP_T, gl.CLAMP);

            gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, 1024, 512, 0, gl.RGBA, gl.UNSIGNED_BYTE, image);

            /*

            gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, 2, 2, 0, gl.RGBA, gl.UNSIGNED_BYTE, new Uint8Array([

                255, 110, 0, 255, 255, 110, 250, 255, 255, 0, 0, 255, 55, 110, 0, 255]));

                */

        }

Solved:

public function addTexture(texture_url: String): Void

    {

        var img: Image = new Image();

        img.onload = function(e)

        {

            texture1 = gl.createTexture();

            gl.activeTexture(gl.TEXTURE1);

            gl.bindTexture(gl.TEXTURE_2D, texture1);

            gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.NEAREST);

            gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.NEAREST);

            gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, img);

        }

        img.src = texture_url;

    }
