Creating link tool

I created panel tool that show url link instead of icons. Source code:

Code:

Ext.define('MVC.view.LinkTool', {
    extend: 'Ext.panel.Tool',
    alias: 'widget.linktool',

    redirectCurrent: false,
    
    renderTpl: ['<a class="{baseCls}-{type} {specificCls}" style="color: rgb(0,255,0); font-size: 12px; line-height: 15px" role="link" href="{link}">{caption}</a>'],

    
    initComponent: function(){
        Ext.applyIf(this.renderData, {
            link: this.link,
            caption: this.caption
        });

        this.callParent();
    },

    handler: function(){
        if(this.redirectCurrent){
            window.location = this.link;
        } else {
            var windowReference = window.open(this.link, this.caption);
            if(windowReference){
                windowReference.focus();
            }
        }
    }
});

When I use this tool in one panel, everything works fine. But when I try use tool in two panels, second is not rendered correct. Parameter left in second link tool is counted from width of first link tool. It means, when i change caption in first link tool, it changes left parameter of second link tool. Here is screenshot from application:

Anyone can help, how to fix it (without setting width parameter)? Here is fiddle example: http://ift.tt/1sFYh2i
