trying to add my custom markdown editor in odoo9 for text area.

Below is the code for widget_text_markdown.js::

odoo.define('web_widget_text_markdown',function (require) {

var core = require('web.core');

var formats = require('web.formats');

var common = require('web.form_common');

var _lt = oe.web._lt;

//oe.web.form.widgets.add('bootstrap_markdown', 'openerp.web_widget_text_markdown.FieldTextMarkDown');

var FieldTextMarkDown = common.AbstractField.extend(common.ReinitializeFieldMixin, {

template: "FieldMarkDown",

display_name: _lt('MarkDown'),

internal_format: 'field_text',

widget_class: 'oe_form_field_bootstrap_markdown',

events: {

'change input': 'store_dom_value' ,

},

init: function (field_manager, node) {

this._super(field_manager, node);

this.$txt = false;

this.internal_set_value(0);

},

parse_value: function(val, def) {

return formats.parse_value(val, {"widget": this.internal_format}, def);

},

initialize_content: function () {

// Gets called at each redraw of widget

// - switching between read-only mode and edit mode

// - BUT NOT when switching to next object.

if(!this.get("effective_readonly")) {

this.$el.find('input').markdown(this.options);

this.setupFocus(this.$('input'));

}

},

store_dom_value: function () {

if (!this.get('effective_readonly')) {

this.internal_set_value(

this.parse_value(

this.$('input').val(),''));

}

},

commit_value: function () {

this.store_dom_value();

return this._super();

},

_get_raw_value: function() {

if (this.$txt === false)

return '';

return this.$txt.val();

},

render_value: function () {

// Gets called at each redraw/save of widget

// - switching between read-only mode and edit mode

// - when switching to next object.

var show_value = this.format_value(this.get('value'), '');

if (!this.get("effective_readonly")) {

this.$input = this.$el.find('input');

this.$input.val(show_value);

} else {

// avoids loading markitup...

marked.setOptions({

highlight: function (code) {

return hljs.highlightAuto(code).value;

}

});

this.$(".oe_form_text_content").html(marked(show_value));

}

},

format_value: function (val, def) {

return formats.format_value(val, {"widget": this.internal_format}, def);

},

});

core.form_widget_registry.add('bootstrap_markdown', FieldTextMarkDown);

return {

FieldTextMarkDown: FieldTextMarkDown,

};

});

After adding this widget to my field it is showing js error that module failed loading
