Hide a button on click

<apex:pageblockButtons > <apex:commandButton action="{!doToggleEditMode}" value="Edit" reRender="myPanel" rendered="{!NOT(bEditMode)}" id="c1" /> <apex:commandButton action="{!doSave}" value="Save" reRender="myPanel" rendered="{!bEditMode}" /> <apex:commandButton value="PRINT" onclick="window.print();"/> <apex:commandButton value="Cancel" action="{!Cancel}"/> <apex:commandButton value="Save" action="{!save}" id="c2"/> </apex:pageblockButtons> 

Extension

public Boolean bEditMode { get { if(bEditMode == null) { bEditmode = false; } return bEditMode; } set; } public PageReference doToggleEditMode() { bEditMode = !bEditMode; return null; } public PageReference doSave() { try { controller.save(); doToggleEditMode(); } catch(Exception ex) { } return null; } 

I want to hide my save button (id="c2") when some one click one the edit button. i tried using j query, but it does not work.(I have a toggle button. when you click on edit button it will change to save. in that case i have two save buttons. I want to hide one of them. ) Does anybody have any idea? Thanks
