Small issues in Tinymce

Hello Praveen,

Excellent code dude!!

But i have found a small issue in tinymce file window.php
/wp-content/plugins/cool-video-gallery/tinymce/window.php

I like to help you my bro

In window.php
comment these lines
//if(window.tinyMCE) {
// window.tinyMCE.execInstanceCommand(‘content’, ‘mceInsertContent’, false, tagtext);
// tinyMCEPopup.editor.execCommand(‘mceRepaint’);
// tinyMCEPopup.close();
//}
//return;

add these lines

if(window.tinyMCE) {

	    /* get the TinyMCE version to account for API diffs */
	    var tmce_ver=window.tinyMCE.majorVersion;

	    if (tmce_ver>="4") {
		window.tinyMCE.execCommand('mceInsertContent', false, tagtext);
	    } else {
		window.tinyMCE.execInstanceCommand('content', 'mceInsertContent', false, tagtext);
	    }

	    tinyMCEPopup.editor.execCommand('mceRepaint');
	    tinyMCEPopup.close();
	    }
	    return;

}

let me know if there is any concern.
Thanks
